Subject: gpio: remove explicit comparison with 0
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2efc6bfadb0b9c873e11ab8da37f4f69aa215d25;p=linux.git

gpio: remove explicit comparison with 0

No need to compare return value with 0. In case of non-zero
return value, the if condition will be true.

This makes intent a bit more clear to the reader.
"if (x) then", compared to "if (x is not zero) then".
