PATCH 1/2 iio: adc: palmas_gpadc: fix NULL dereference on rmmod

From: Patrik Dahlström <[email protected]>

[ Upstream commit 49f76c499d38bf67803438eee88c8300d0f6ce09 ]

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

PATCH 2/2 ASoC: Intel: bytcr_rt5640: Add quirk for the Acer Iconia One 7 B1-750

From: Hans de Goede <[email protected]>

[ 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.
