With subfacets, we'd expect megaflow updates message to carry
the original micro flow. If not, EINVAL is returned and kernel
logs an error message. Now that the user space subfacet layer is
removed, it is expected that flow updates can arrive with a
micro flow other than the original. Change the return code to
EEXIST and remove the kernel error log message.

We've seen often problems after suspend/resume on Acer Aspire One

out that some COEFs doesn't work and triggers the codec communication

Since these magic COEF setups are specific to ALC269VB for some PLL

The common clock framework considers NULL a valid clock
reference. This makes handling optional clocks simple, in that if the
optional clock is not available, a NULL reference can be used in the
place of a real clock, simplifying the clock consumer.
Extend this concept to the phy consumer API. A NULL can be passed to
the release calls, the phy_init() and phy_exit() calls, and
phy_power_on() and phy_power_off() and a NOP is performed.

When a Gigabit PHY device is connected to a 10/100Mbits capable Ethernet
MAC, the driver will restrict the phydev->supported modes to mask off
Gigabit. If the Gigabit PHY comes out of reset with the Gigabit features
set by default in MII_CTRL1000, it will keep advertising these feature,
so by the time we call genphy_config_advert(), the condition on
phydev->supported having the Gigabit features on is false, and we do not
update MII_CTRL1000 with updated values, and we keep advertising Gigabit
features, eventually configuring the PHY for Gigabit whilst the Ethernet
MAC does not support that.
This patches fixes the problem by ensuring that the Gigabit feature bits
are always cleared in MII_CTRL1000, if the PHY happens to be a Gigabit
PHY, and then, if Gigabit features are supported, setting those and
updating MII_CTRL1000 accordingly.

====================
bonding: Fix some issues for fail_over_mac
The parameter fail_over_mac only affect active-backup mode, if it was
set to active or follow and works with other modes, just like RR or XOR
mode, the bonding could not set all slaves to the master's address, it
will cause the slave could not work well with master.
v1->v2: According Jay's suggestion, that we should permit setting an option
at any time, but only have it take effect in active-backup mode, so
I add mode checking together with fail_over_mac during enslavement and
rebuild the patches.
v2->v3: The correct way to fix the problem is that we should not add restrictions when
setting options, just need to modify the bond enslave and removal processing
to check the mode in addition to fail_over_mac when setting a slave's MAC during
enslavement. The change active slave processing already only calls the fail_over_mac
function when in active-backup mode.

The error is in calling to_usb_device(hsotg->dev), since ->dev

Even though we make sure PowerSave is not enabled by default
by disabling the flag, WIPHY_FLAG_PS_ON_BY_DEFAULT on init,
PS could be enabled by userspace based on various factors
like battery usage etc. Since PS in ath9k is just broken
and has been untested for years, remove support for it, but
allow a user to explicitly enable it using a module parameter.

mac80211 ->sta_rc_update() callback must be atomic. Since we have to
take mutex and do other operations that can sleep when sending fimrware
commands to device, the only option to satisfy atomicity requirement of
->sta_rc_update(), that I can see, is introduce work_struct and defer
uploading new rates to that work.
