Subject: s390/crash: remove redundant panic() on save area allocation failure
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=86caa4b678956bc19567256dd8422f3978620897;p=linux.git

s390/crash: remove redundant panic() on save area allocation failure

Make save_area_alloc() return classic NULL on allocation failure.
The only caller smp_save_dump_cpus() does check the return value
already and panics if NULL is returned.
