[PATCH -next] powerpc/powermac: Fix symbol not declared warnings

From: Chen Lifu
Date: Fri Aug 19 2022 - 03:46:28 EST


1. ppc_override_l2cr and ppc_override_l2cr_value are only used in
l2cr_init() function, so move them inside the function.
2. has_l2cache is not used outside of the file, so mark it static, and
do not initialise statics to 0.

Fixes the following warning:

arch/powerpc/platforms/powermac/setup.c:74:5: warning: symbol 'ppc_override_l2cr' was not declared. Should it be static?
arch/powerpc/platforms/powermac/setup.c:75:5: warning: symbol 'ppc_override_l2cr_value' was not declared. Should it be static?
arch/powerpc/platforms/powermac/setup.c:76:5: warning: symbol 'has_l2cache' was not declared. Should it be static?
