Subject: lockd: fix decoder callback prototypes
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=04000564c1fc72770e4946cc3adb3ea9cd544bb2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

lockd: fix decoder callback prototypes

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