memstick r592: make memstick_debug_get_tpc_name() static

From: Arnd Bergmann <[email protected]>

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.

Fixes 926341250102 ("memstick: add driver for Ricoh R5C592 card reader")
