From 73b8e217fe6ffbb98b6086654bd4f812839e4b5a Mon Sep 17 00:00:00 2001 From: Qi Zheng Date: Thu, 2 Feb 2023 17:32:55 +0800 Subject: [PATCH] bonding: fix error checking in bond_debug_reregister() [ Upstream commit cbe83191d40d8925b7a99969d037d2a0caf69294 ] Since commit ff9fb72bc077 ("debugfs: return error values, not NULL") changed return value of debugfs_rename() in error cases from %NULL to %ERR_PTR(-ERROR), we should also check error values instead of NULL.
