X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d16073389bb48a2caf7c62cd7089a2009c8717b8;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

lockd: fix encoder callback prototypes

Declare the p_encode callbacks with the proper prototype instead of
casting to kxdreproc_t and losing all type safety.
