From d2be3667f3769b3c60aa294ef7f2b03d1b16559c Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Thu, 11 May 2017 19:29:40 +0100 Subject: [PATCH] ethernet: aquantia: remove redundant checks on error status The error status err is initialized as zero and then being checked several times to see if it is less than zero even when it has not been updated. It may seem that the err should be assigned to the return code of the call to the various *offload_en_set calls and then we check for failure, however, these functions are void and never actually return any status. Since these error checks are redundant we can remove these as well as err and the error exit label err_exit.
