From bbc404d20d1b46d89b461918bc44587620eda200 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sat, 20 Jan 2024 18:25:36 +0100 Subject: [PATCH] ixgbe: Fix an error handling path in ixgbe_read_iosf_sb_reg_x550() All error handling paths, except this one, go to 'out' where release_swfw_sync() is called. This call balances the acquire_swfw_sync() call done at the beginning of the function. Branch to the error handling path in order to correctly release some resources in case of error.
