ALSA: usb-audio: Use snd_usb_ctl_msg() for Native Instruments quirk

snd_nativeinstruments_control_get() uses a stack as a buffer for
usb_control_msg(), but it's basically not allowed.  Replace the call
with a safer helper, snd_usb_ctl_msg(), instead.

thermal: cpu_cooling: Update always cpufreq policy with thermal constraints

Existing code updates cupfreq policy only while executing
cpufreq_apply_cooling() function (i.e. when notify_device != NOTIFY_INVALID).
It doesn't apply constraints when cpufreq policy update happens from any other
place but it should update the cpufreq policy with thermal constraints every
time when there is a cpufreq policy update, to keep state of
cpufreq_cooling_device and max_feq of cpufreq policy in sync. For instance
while resuming cpufreq updates cpufreq_policy and it restores default
policy->usr_policy values irrespective of cooling device's cpufreq_state since
notification gets missed because (notify_device == NOTIFY_INVALID).
Another problem, is that userspace is able to change max_freq irrespective of
cooling device's state, as notification gets missed.

This patch modifies code to maintain a global cpufreq_dev_list and applies
constraints of all matching cooling devices for policy's cpu when there is any
policy update(ends up applying the lowest max_freq among the matching cpu
cooling devices).

This patch also removes redundant check (max_freq > policy->user_policy.max),
as cpufreq framework takes care of user_policy constraints already where ever
required, otherwise its causing an issue while increasing max_freq in normal
scenerio as it restores max_freq with policy->user_policy.max which is old
(smaller) value.

ALSA: hda - One more HP machine needs to change mute led quirk

The machine originally use the quirk ALC269_FIXUP_HP_GPIO_MIC1_LED,
but the LED doesn't work at all.

After this change, the machine will change to use
ALC269_FIXUP_HP_MUTE_LED_MIC1 through pin_fixup_tbl[], and the LED
works well.

thermal: Exynos: Deletion of unnecessary checks before two function calls

The functions cpufreq_cooling_unregister() and thermal_zone_device_unregister()
test whether their argument is NULL and then return immediately.
Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
