X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d721109611fb94aff53c2397859046e5f92f55ae;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

kbuild: fixdep: optimize code slightly

If the target string matches "CONFIG_", move the pointer p
forward.  This saves several 7-chars adjustments.
