If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 12e8019e683678656271e29ed55e4a1cfad6473a Author: Arnd Bergmann <arnd@xxxxxxxx> Date: Tue May 16 22:27:04 2023 +0200 memstick r592: make memstick_debug_get_tpc_name() static [ Upstream commit 434587df9f7fd68575f99a889cc5f2efc2eaee5e ] There are no other files referencing this function, apparently it was left global to avoid an 'unused function' warning when the only caller is left out. With a 'W=1' build, it causes a 'missing prototype' warning though: drivers/memstick/host/r592.c:47:13: error: no previous prototype for 'memstick_debug_get_tpc_name' [-Werror=missing-prototypes] Annotate the function as 'static __maybe_unused' to avoid both problems.
