currently, when clk_get(NULL,"usb-device") fail, it does not

this patch use new interface devm_xxx instead of xxx then
we no need to care about cleanup resource in err case that is boring

If there is a rea
tty_port_init() zeroes out the tty port, which means that we have to set the
ops pointer /after/, not before this call. Otherwise, tty_port_open will crash
when it tries to deref ops, which is now a NULL pointer.

I'm announcing the release of the 3.6.11.3 kernel.
The updated 3.6.11.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git
v3.6-stable
The patch can be downloaded at:

From: Benoit Goby
Below is a patch from android kernel that detects a driver suspend/resume
lockup and captures dump in the kernel log. Please review and provide
comments.
Rather than hard-lock the kernel, dump the suspend/resume thread stack and
BUG() when a driver takes too long to suspend/res
Power management debug option to configure device suspend/resume watchdogs.
Available options are:
1. Enable/disable the feature.
2. Select triggered watchdog action between:
- system panic (default)
- dump stacktrace
- log event
3. Select timeout value for the watchdo
Hi all,
Attached are two patches addressing comments on the implementation
of device suspend (and resume) watchdogs from the android kernel. I have
squashed changes for the suspend and resume watchdogs as they address
pretty much the same functionality, and also added compile-time
configurability o

I started testing the new NOHZ_FULL in the kernel and had some issues,
so I started function tracing and this bug report came out:

Frederic,
Can you take these patches. The first patch will need to get an
ack by one of the x86 maintainers. That one adds a new schedule_preempt_user()
that is called before going back to user space in order to safely
switch from user_context before calling schedule.
The second patch prevents LO
If the user configures NO_HZ_FULL and defines nohz_full=XXX on the
kerenl command line, or enables NO_HZ_FULL_ALL, but nohz fails
due to the machine having a unstable clock, warn about it.
We do not want users thinking that they are getting the benefit
of nohz when their machine can not support it
Trying to test the nohz_full code, I was not able to get it to work.
Finally I enabled the tick_stop tracepoint and it showed:
tick_stop:success=no msg=perf events running
I talked to Frederic Weisbecker about this and he informed me that
perf is used by the lockup detector. I checke

Fengguang's kbuild bot found a compile error on one arch with this patch, so
I've pushed a new version to the git tree.

Add support for TEA5757 tuner on MediaForte M56VAP sound+modem+radio card.
The GPIO connection type is automatically detected (like snd-fm801 driver).
Also add a safety subsystem vendor check to skip radio detection if vendor
differs from ESS (so we don't touch GPIOs on laptops).
Tested with SF64
