When insert_inode_locked() fails in ext2_new_inode() it most likely means inode
bitmap got corrupted and we allocated again inode which is already in use. Also
doing unlock_new_inode() during error recovery is wrong since the inode does
not have I_NEW set. Fix the problem by informing about filesystem error and
jumping to fail: (instead of fail_drop:) which doesn't call unlock_new_inode().

Now that a regulator device for controlling the codec chip reset state
over a platform agnostic regulator API is available on the only board
using this driver so far, extend the driver with a bias control function
which will request virtual power to the codec chip from that virtual
regulator, and will supersede the present implementation existing at the
sound card level.
Thanks to the regulator sharing mechanism, both the old (the sound card)
and the new (the codec) implementations should coexist smoothly until
the sound card file is updated. For this to work as expected, update the
sound card .set_bias_level callback to not touch codec->dapm.bias_level.
While extending the cx20442 structure, drop unused control_type member.
Created against linxu-3.2-rc6, tested on top of patch 1/4 "ARM: OMAP1:
ams-delta: set up a regulator over the modem reset GPIO pin".

With some buggy devices, the usb-audio driver may give "frame xxx active"
kernel messages too often. Better to keep it as debug-only using
snd_printdd(), and also add the rate-limit for avoiding floods.

cache flushing code is finished in platform_cpu_die() before

Both ext3 and ext4 put the half-created symlink inode into the orphan list
for a while (see the comment in ext[34]_symlink() for gory details). Then,
if everything went fine, they pull it out of the orphan list and bump the
link count back to 1. The thing is, inc_nlink() is going to complain about
seeing somebody changing i_nlink from 0 to 1. With a good reason, since
normally something like that is a bug. Explicit set_nlink(inode, 1) does
the same thing as inc_nlink() here, but it does *not* complain - exactly
because it should be usable in strange situations like this one.
