[PATCH AUTOSEL 6.6 01/33] Input: elantech - fix touchpad state on resume for Lenovo N24

[Sasha Levin]

From: Jonathan Denose <jdenose@google.com>

[ Upstream commit a69ce592cbe0417664bc5a075205aa75c2ec1273 ]

The Lenovo N24 on resume becomes stuck in a state where it
sends incorrect packets, causing elantech_packet_check_v4 to fail.
The only way for the device to resume sending the correct packets is for
it to be disabled and then re-enabled.

This change adds a dmi check to trigger this behavior on resume.

[PATCH AUTOSEL 6.6 16/33] Input: ads7846 - use spi_device_id table

[Sasha Levin]

From: Alexander Stein <alexander.stein@ew.tq-group.com>

[ Upstream commit 7c7b1be19b228b450c2945ec379d7fc6bfef9852 ]

As the driver supports more devices over time the single MODULE_ALIAS
is complete and raises several warnings:
SPI driver ads7846 has no spi_device_id for ti,tsc2046
SPI driver ads7846 has no spi_device_id for ti,ads7843
SPI driver ads7846 has no spi_device_id for ti,ads7845
SPI driver ads7846 has no spi_device_id for ti,ads7873

Fix this by adding a spi_device_id table and removing the manual
MODULE_ALIAS.
