Subject: openrisc: Add prototype for die to bug.h
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=31c67b5fabe351644b2612c6ba75da70aeb417b1;p=users%2Fjedix%2Flinux-maple.git

openrisc: Add prototype for die to bug.h

When compiling with W=1 enabling -Wmissing-prototypes the compiler
warns:

  arch/openrisc/kernel/traps.c:221:17: sing-prototypesrror: no previous prototype for 'die' [-Werror=missing-prototypes]

Fix by adding the prototype to the appropriate header file and including
the header file in the appropriate C files.

Reported-by: Arnd Bergmann <arnd@arndb.de>
Closes: https://lore.kernel.org/linux-kernel/20230810141947.1236730-17-arnd@kernel.org/
