Subject: staging: rtlwifi: remove memset before memcpy
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=30207d7b640cd27a814abbc657c911121160dc10;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

staging: rtlwifi: remove memset before memcpy

calling memcpy immediately after memset with the same region of memory
makes memset redundant.
