From: Shyam Saini Date: Sat, 14 Jan 2017 01:17:40 +0000 (+0530) Subject: cxgb4: Remove redundant memset before memcpy X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ca4b5eb88aa0da96ede750d8b894e7079612aa65;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git cxgb4: Remove redundant memset before memcpy The region set by the call to memset, immediately overwritten by the subsequent call to memcpy and thus makes the memset redundant. Also remove the memset((&info, 0, sizeof(info)) on line 398 because info is memcpy()'ed to before being used in the loop and it isn't used outside of the loop.
