[PATCH] gpio: remove explicit comparison with 0

[Saiyam Doshi <saiyamdoshi.in@xxxxxxxxx>]

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".
