Subject: i40e: Remove redundant memset
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4dec7d045d6d20afe794adbda5b6da2fe5d63a35;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

i40e: Remove redundant memset

Remove redundant call to memset before a call to memcpy.

The Coccinelle semantic patch used to make this change is as follows:
@@
expression e1,e2,e3,e4;
@@

- memset(e1,e2,e3);
  memcpy(e1,e4,e3);
