Subject: Input: penmount - simplify unregister procedure
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c3a01ba9e45f01c6505a41efb33c420a0c959eb3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Input: penmount - simplify unregister procedure

Since touchscreen driver does not handle any events to be sent to the
device we can close serio port first and then unregister the input device.
