Subject: sh: Shut up compiler warnings in __do_page_fault().
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b8947444a738c6407466244c60e9e4a2999af555;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

sh: Shut up compiler warnings in __do_page_fault().

GCC doesn't seem to be able to figure this one out for
itself, so just shut it up..

  CC      arch/sh/mm/fault.o
arch/sh/mm/fault.c: In function '__do_page_fault':
arch/sh/mm/fault.c:288: warning: 'ptl' may be used uninitialized in this function
