Subject: Input: parkbd - clear unused function pointers
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0c6da0733bff3bc7aaa1dcd63fefdbbca5a7a5f8;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Input: parkbd - clear unused function pointers

parkbd_parport_cb is a local uninitialized structure and the member
function pointers will be pointing to arbitrary locations unless they
are cleared.

Fixes: 33ca8ab97cbb ("Input: parkbd - use parallel port device model")
