[PATCH AUTOSEL 6.1 2/5] scsi: ufs: core: Bypass quick recovery if force reset is needed

[Sasha Levin]

From: Peter Wang <peter.wang@mediatek.com>

[ Upstream commit 022587d8aec3da1d1698ddae9fb8cfe35f3ad49c ]

If force_reset is true, bypass quick recovery.  This will shorten error
recovery time.

[PATCH AUTOSEL 6.1 3/5] ALSA: hda/generic: Add a helper to mute speakers at suspend/shutdown

[Sasha Levin]

From: Takashi Iwai <tiwai@suse.de>

[ Upstream commit 6cd23b26b348fa52c88e1adf9c0e48d68e13f95e ]

Some devices indicate click noises at suspend or shutdown when the
speakers are unmuted.  This patch adds a helper,
snd_hda_gen_shutup_speakers(), to work around it.  The new function is
supposed to be called at suspend or shutdown by the codec driver, and
it mutes the speakers.

The mute status isn't cached, hence the original mute state will be
restored at resume again.

[PATCH AUTOSEL 6.1 5/5] Input: MT - limit max slots

[Sasha Levin]

From: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp>

[ Upstream commit 99d3bf5f7377d42f8be60a6b9cb60fb0be34dceb ]

syzbot is reporting too large allocation at input_mt_init_slots(), for
num_slots is supplied from userspace using ioctl(UI_DEV_CREATE).

Since nobody knows possible max slots, this patch chose 1024.
