Subject: [PATCH 769/826] gcc-9: don't warn about uninitialized variable
|
|
|
|
commit cf676908846a06443fa5e6724ca3f5dd7460eca1 upstream.
|
|
|
|
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.
