From: Linus Torvalds Date: Wed, 1 May 2019 18:07:40 +0000 (-0700) Subject: gcc-9: don't warn about uninitialized variable X-Git-Tag: microblaze-v5.4-rc1~892 X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=cf676908846a06443fa5e6724ca3f5dd7460eca1;p=linux-2.6-microblaze.git gcc-9: don't warn about uninitialized variable I'm not sure what made gcc warn about this code now. The 'ret' variable does end up initialized in all cases, but it's definitely not obvious, so the compiler is quite reasonable to warn about this. So just add initialization to make it all much more obvious both to compilers and to humans.
