From: Jakob Koschel <jakobkoschel@gmail.com> stable inclusion from stable-v5.10.122 commit 4610b067615f3ff97dec9ad576d6031072e0eb18 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5W6OE Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 84ef256550196bc06e6849a34224c998b45bd557 ] If the list does not exit early then data == NULL and 'module' does not point to a valid list element. Using 'module' in such a case is not valid and was therefore removed.
