In function dsi_compute_interleave_lp(), the escape clock/LP clock time period
is calculated incorrectly. The escape clock/LP clock is calculated as:
LP Clock(Hz) = DSI_FCLK(Hz) / lp_clk_div
Since we are calculating the time period of LP clock, the LP clock divider
should be multiplied with the time period of DSI_FCLK.
Calculating incorrect value of txclkesc results in incorrect calculation of LP
interleaving parameters, it also creates a possibility of a divide by zero
error.

The devm_kzalloc function eliminates the need for manual resource releasing
and simplify error handling. Resources allocated by devm_* are freed
automatically on driver detach.
Thus adding kfree calls here will introduce double free bug.
The memory of desc array and the pointers to the rdev[] are allocated by
devm_kzalloc call for struct palmas_pmic.
struct palmas_pmic {
struct palmas *palmas;
struct device *dev;
struct regulator_desc desc[PALMAS_NUM_REGS];
struct regulator_dev *rdev[PALMAS_NUM_REGS];
struct mutex mutex;

pm_runtime_put_sync() in dss_runtime_put() returns -EBUSY when any child
of dss is still enabled. This happens, for example, when a display
output is enabled and one dumps the clocks via debugfs. This causes
dss_runtime_get & put to be called.
While I couldn't find anything about this in the documentation and it
wasn't immediately clear from runtime_pm code, it looks to me that
pm_runtime_put_sync() returns -EBUSY to inform that things went fine,
but the device could not be turned off as there are still child devices
that are enabled. This is not a problem.
This patch skips the WARN_ON if pm_runtime_put_sync() returns -EBUSY.

Initial IVB support went into turbostat in Linux-3.1:
553575f1ae
(tools turbostat: recognize and run properly on IVB)
However, when running on IVB, turbostat would fail
to report the new couters added with SNB, c7, pc2 and pc7.
So in scenarios where these counters are non-zero on IVB,
turbostat would report erroneous residencey results.
In particular c7 time would be added to c1 time,
since c1 time is calculated as "that which is left over".
Also, turbostat reports MHz capabilities when passed
the "-v" option, and it would incorrectly report 133MHz
bclk instead of 100MHz bclk for IVB, which would inflate
GHz reported with that option.
This patch is a backport of a fix already included in turbostat v2.

New tmpfs use of !PageUptodate pages for fallocate() is triggering the
WARNING: at mm/page-writeback.c:1990 when __set_page_dirty_nobuffers()
is called from migrate_page_copy() for compaction.
It is anomalous that migration should use __set_page_dirty_nobuffers()
on an address_space that does not participate in dirty and writeback
accounting; and this has also been observed to insert surprising dirty
tags into a tmpfs radix_tree, despite tmpfs not using tags at all.
We should probably give migrate_page_copy() a better way to preserve the
tag and migrate accounting info, when mapping_cap_account_dirty(). But
that needs some more work: so in the interim, avoid the warning by using
a simple SetPageDirty on PageSwapBacked pages.

The comment above it says "Stat data, not accessed from path walking",
but in fact some of inode fields we use for the common stat data was way
down at the end of the inode, causing unnecessary cache misses for the
common stat operations.
The inode structure is pretty big, and this can change padding depending
on field width, but at least on the common 64-bit configurations this
doesn't change the size. Some of our inode layout has historically been
to tro to avoid unnecessary padding fields, but cache locality is at
least as important for layout, if not more.
Noticed by looking at kernel profiles, and noticing that the "i_blkbits"

Fix the issue of C_CAN interrupts getting disabled forever when canconfig
utility is used multiple times. According to NAPI usage we disable all
the hardware interrupts in ISR and re-enable them in poll(). Current
implementation calls napi_enable() after hardware interrupts are enabled.
If we get any interrupts between these two steps then we do not process
those interrupts because napi is not enabled. Mostly these interrupts
come because of STATUS is not 0x7 or ERROR interrupts. If napi_enable()
happens before HW interrupts enabled then c_can_poll() function will be
called eventual re-enabling.
This patch moves the napi_enable() call before interrupts enabled.

This patch fixes an interrupt thrash issue with c_can driver.
In c_can_isr() function interrupts are disabled and enabled only in
c_can_poll() function. c_can_isr() & c_can_poll() both read the
irqstatus flag. However, irqstatus is always read as 0 in c_can_poll()
because all C_CAN interrupts are disabled in c_can_isr(). This causes
all interrupts to be re-enabled in c_can_poll() which in turn causes
another interrupt since the event is not really handled. This keeps
happening causing a flood of interrupts.
To fix this, read the irqstatus register in isr and use the same cached
value in the poll function.

This patch fixes an issue with transmit routine, which causes
"can_put_echo_skb: BUG! echo_skb is occupied!" message when
using "cansequence -p" on D_CAN controller.
In c_can driver, while transmitting packets tx_echo flag holds
the no of can frames put for transmission into the hardware.
As the comment above c_can_do_tx() indicates, if we find any packet
which is not transmitted then we should stop looking for more.
In the current implementation this is not taken care of causing the
said message.
Also, fix the condition used to find if the packet is transmitted
or not. Current code skips the first tx message object and ends up
checking one extra invalid object.
While at it, fix the comment on top of c_can_do_tx() to use the
terminology "packet" instead of "package" since it is more
standard.

Prior to this patch, the CPU side of a DAI link was specified using a
single name. Often, this was the result of calling dev_name() on the
device providing the DAI, but in the case of a CPU DAI driver that
provided multiple DAIs, it needed to mix together both the device name
and some device-relative name, in order to form a single globally unique
name.
However, the CODEC side of the DAI link was specified using separate
fields for device (name or OF node) and device-relative DAI name.
This patch allows the CPU side of a DAI link to be specified in the same
way as the CODEC side, separating concepts of device and device-relative
DAI name.
I believe this will be important in multi-codec and/or dynamic PCM
scenarios, where a single CPU driver provides multiple DAIs, while also
booting using device tree, with accompanying desire not to hard-code the
CPU side device's name into the original .cpu_dai_name field.
Ideally, both the CPU DAI and CODEC DAI loops in soc_bind_dai_link()
would now be identical. However, two things prevent that at present:
1) The need to save rtd->codec for the CODEC side, which means we have
to search for the CODEC explicitly, and not just the CODEC side DAI.
2) Since we know the CODEC side DAI is part of a codec, and not just
a standalone DAI, it's slightly more efficient to convert .codec_name/
.codec_of_node into a codec first, and then compare each DAI's .codec
field, since this avoids strcmp() on each DAI's CODEC's name within
the loop.
However, the two loops are essentially semantically equivalent.
