#     powerpc: Remove variable ‘path’ since not used
#     
#     In commit eab00a208eb6 ("powerpc: Move `path` variable inside
#     DEBUG_PROM") DEBUG_PROM sentinels were added to silence a warning
#     (treated as error with W=1):
#     
#       arch/powerpc/kernel/prom_init.c:1388:8: error: variable ‘path’ set but not used [-Werror=unused-but-set-variable]
#     
#     Rework the original patch and simplify the code, by removing the
#     variable ‘path’ completely. Fix line over 90 characters.

WARNING: vmlinux.o(.text+0x30ba): Section mismatch in reference from the variable start_here_multiplatform to the function .init.text:.early_setup()
The function start_here_multiplatform() references
the function __init .early_setup().
This is often because start_here_multiplatform lacks a __init 
annotation or the annotation of .early_setup is wrong.
