[PATCH] memstick: r592: add function declaration

[Baoyou Xie]

We get 1 warning when building kernel with W=1:
drivers/memstick/host/r592.c:50:13: warning: no previous prototype for 'memstick_debug_get_tpc_name' [-Wmissing-prototypes]

In fact, this function need be declared in a header files.

So this patch adds function declaration in
drivers/memstick/host/r592.h.
