Subject: staging: ks7010: Remove unnecessary variable used to store return value
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0525a57b1879370fe0e330708bda3b1c25c937f1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

staging: ks7010: Remove unnecessary variable used to store return value

This patch removes an unnecessary variable used to store return values in order
to reduce memory usage.
Done using coccinelle:
@@
type T;
constant C;
identifier ret;
@@
- T ret = C;
... when != ret
return
- ret
+ C
;
