Subject: Staging: rtl8192u: Remove useless type conversion
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=efdcb35a82fdd6e91b890efd3d5a5d4045e64c08;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Staging: rtl8192u: Remove useless type conversion

Some type conversions like casting a pointer to a pointer of same type,
casting to the original type using addressof(&) operator etc. are not
needed. Therefore, remove them. Done using coccinelle:

@@
type t;
t *p;
t a;
@@
(
- (t)(a)
+ a
|
- (t *)(p)
+ p
|
- (t *)(&a)
+ &a
)
