From eeae4230dbf181f318a6604a74106765e0c66248 Mon Sep 17 00:00:00 2001 From: Tong Zhang Date: Sat, 22 May 2021 00:37:25 -0400 Subject: misc: alcor_pci: fix inverted branch condition commit 281e468446994a7672733af2bf941f4110d4a895 upstream. This patch fixes a trivial mistake that I made in the previous attempt in fixing the null bridge issue. The branch condition is inverted and we should call alcor_pci_find_cap_offset() only if bridge is not null.
