[PATCH 07/14] panic: hide unused global functions

Arnd Bergmann
2023-05-17T13:13:06Z

Building with W=1 shows warnings about two functions that have
no declaration or caller in certain configurations:

kernel/panic.c:688:6: error: no previous prototype for 'warn_slowpath_fmt' [-Werror=missing-prototypes]
kernel/panic.c:710:6: error: no previous prototype for '__warn_printk' [-Werror=missing-prototypes]

Enclose the definition in the same #ifdef check as the declaration.
