From 2efc6bfadb0b9c873e11ab8da37f4f69aa215d25 Mon Sep 17 00:00:00 2001 From: Saiyam Doshi Date: Sat, 7 Sep 2019 23:09:10 +0530 Subject: 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".
