SubjectRe: [PATCH 1/1] [media] mb86a20s: always initialize a return value
From
Date
Hello,

I sent the following patch (available on
https://patchwork.kernel.org/patch/9325035/) a few weeks ago and got no
feedback even though the bug it fixes seems to still exist in
linux-next. Did I do something wrong? Should I consider this patch to be
rejected?

Thanks,
Nicolas
