[PATCH AUTOSEL 5.15 1/7] ASOC: Intel: sof_sdw: add quirk for Intel 'Rooks County' NUC M15

[Sasha Levin]

From: Eugene Huang <eugene.huang99@gmail.com>

[ Upstream commit 3c728b1bc5b99c5275ac5c7788ef814c0e51ef54 ]

Same quirks as the 'Bishop County' NUC M15, except the rt711 is in the
'JD2 100K' jack detection mode.

[PATCH AUTOSEL 5.15 2/7] ASoC: soc-pcm: fix hw->formats cleared by soc_pcm_hw_init() for dpcm

[Sasha Levin]

From: Shengjiu Wang <shengjiu.wang@nxp.com>

[ Upstream commit 083a25b18d6ad9f1f540e629909aa3eaaaf01823 ]

The hw->formats may be set by snd_dmaengine_pcm_refine_runtime_hwparams()
in component's startup()/open(), but soc_pcm_hw_init() will init
hw->formats in dpcm_runtime_setup_fe() after component's startup()/open(),
which causes the valuable hw->formats to be cleared.

So need to store the hw->formats before initialization, then restore
it after initialization.

[PATCH AUTOSEL 5.15 3/7] x86/hyperv: Block root partition functionality in a Confidential VM

[Sasha Levin]

From: Michael Kelley <mikelley@microsoft.com>

[ Upstream commit f8acb24aaf89fc46cd953229462ea8abe31b395f ]

Hyper-V should never specify a VM that is a Confidential VM and also
running in the root partition.  Nonetheless, explicitly block such a
combination to guard against a compromised Hyper-V maliciously trying to
exploit root partition functionality in a Confidential VM to expose
Confidential VM secrets. No known bug is being fixed, but the attack
surface for Confidential VMs on Hyper-V is reduced.

[Sasha Levin]

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit e38c5e80c3d293a883c6f1d553f2146ec0bda35e ]

The Acer Iconia One 7 B1-750 tablet mostly works fine with the defaults
for an Bay Trail CR tablet. Except for the internal mic, instead of
an analog mic on IN3 a digital mic on DMIC1 is uses.

Add a quirk with these settings for this tablet.

[PATCH AUTOSEL 5.15 6/7] selftests mount: Fix mount_setattr_test builds failed

[Sasha Levin]

From: Anh Tuan Phan <tuananhlfc@gmail.com>

[ Upstream commit f1594bc676579133a3cd906d7d27733289edfb86 ]

When compiling selftests with target mount_setattr I encountered some errors with the below messages:
mount_setattr_test.c: In function ‘mount_setattr_thread’:
mount_setattr_test.c:343:16: error: variable ‘attr’ has initializer but incomplete type
  343 |         struct mount_attr attr = {
      |                ^~~~~~~~~~

These errors might be because of linux/mount.h is not included. This patch resolves that issue.
