X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7499b702f0873b670cbd769c9bfeb437e9fa4c55;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

staging: rt18188eu: Remove useless cast on NULL

Cast on NULL to a pointer type is not required. This
patch removes NULL casted to some pointer type.

The sematic patch used is:
@r@
type T;
@@
- (T *)NULL
+ NULL

Build tested it.
