Subject[PATCH 5.4 162/191] bnxt_en: Remove unnecessary NULL checks for fw_health
Date
From: Vasundhara Volam <vasundhara-v.volam@broadcom.com>

[ Upstream commit 0797c10d2d1fa0d6f14612404781b348fc757c3e ]

After fixing the allocation of bp->fw_health in the previous patch,
the driver will not go through the fw reset and recovery code paths
if bp->fw_health allocation fails. So we can now remove the
unnecessary NULL checks.
