Subject: drivers: staging: nvec: remove bogus reset command for PS/2 interface
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d8f8a74d5fece355d2234e1731231d1aebc66b38;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drivers: staging: nvec: remove bogus reset command for PS/2 interface

This command was sent behind serio's back and the answer to it was
confusing atkbd probe function which lead to the elantech touchpad
getting detected as a keyboard.

To prevent this from happening just let every party do its part of the
job.
