[PATCH AUTOSEL 5.4 1/3] iio: adc: palmas_gpadc: fix NULL dereference on rmmod

[Sasha Levin]

From: Patrik Dahlström <risca@dalakolonin.se>

[ Upstream commit 49f76c499d38bf67803438eee88c8300d0f6ce09 ]

Calling dev_to_iio_dev() on a platform device pointer is undefined and
will make adc NULL.

[PATCH AUTOSEL 5.4 2/3] ASoC: Intel: bytcr_rt5640: Add quirk for the Acer Iconia One 7 B1-750

[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 5.4 3/3] asm-generic/io.h: suppress endianness warnings for readq() and writeq()

[Sasha Levin]

From: Vladimir Oltean <vladimir.oltean@nxp.com>

[ Upstream commit d564fa1ff19e893e2971d66e5c8f49dc1cdc8ffc ]

Commit c1d55d50139b ("asm-generic/io.h: Fix sparse warnings on
big-endian architectures") missed fixing the 64-bit accessors.

Arnd explains in the attached link why the casts are necessary, even if
__raw_readq() and __raw_writeq() do not take endian-specific types.
