From b4f74051165560aa81814433dea7e6eb0bdb32b9 Mon Sep 17 00:00:00 2001 From: Kalesh AP Date: Wed, 2 Oct 2019 10:17:38 -0700 Subject: [PATCH] net/bnxt: remove unnecessary return check HWRM_CHECK_RESULT_SILENT() returns if the HWRM command fails. There is no need to check the return value after this call.
