Input: ati_remote2 - add missing newlines when printing module parameters

2020-10-14T08:33:06+00:00

commit 37bd9e803daea816f2dc2c8f6dc264097eb3ebd2 upstream.

When I cat some module parameters by sysfs, it displays as follows. It's
better to add a newline for easy reading.

root@syzkaller:~# cat /sys/module/ati_remote2/parameters/mode_mask
0x1froot@syzkaller:~# cat /sys/module/ati_remote2/parameters/channel_mask

Input: i8042 - add nopnp quirk for Acer Aspire 5 A515

2020-10-07T06:01:24+00:00

commit 5fc27b098dafb8e30794a9db0705074c7d766179 upstream.

Touchpad on this laptop is not detected properly during boot, as PNP
enumerates (wrongly) AUX port as disabled on this machine.

Fix that by adding this board (with admittedly quite funny DMI
identifiers) to nopnp quirk list.

Input: i8042 - add Entroware Proteus EL07R4 to nomux and reset lists

commit c4440b8a457779adeec42c5e181cb4016f19ce0f upstream.

The keyboard drops keypresses early during boot unless both the nomux
and reset quirks are set. Add DMI table entries for this.

Input: sentelic - fix error return when fsp_reg_write fails

2020-08-21T11:05:36+00:00

[ Upstream commit ea38f06e0291986eb93beb6d61fd413607a30ca4 ]

Currently when the call to fsp_reg_write fails -EIO is not being returned
because the count is being returned instead of the return value in retval.
Fix this by returning the value in retval instead of count.

Input: elan_i2c - only increment wakeup count on touch

2020-07-29T08:18:38+00:00

[ Upstream commit 966334dfc472bdfa67bed864842943b19755d192 ]

This moves the wakeup increment for elan devices to the touch report.
This prevents the drivers from incorrectly reporting a wakeup when the
resume callback resets then device, which causes an interrupt to
occur.

Input: i8042 - add Lenovo XiaoXin Air 12 to i8042 nomux list

2020-07-22T07:33:13+00:00

commit 17d51429da722cd8fc77a365a112f008abf4f8b3 upstream.

This fixes two finger trackpad scroll on the Lenovo XiaoXin Air 12.
Without nomux, the trackpad behaves as if only one finger is present and
moves the cursor when trying to scroll.
