From 63d51e591931b878be7a16dacb37868a1e7ae8d1 Mon Sep 17 00:00:00 2001 From: Nicholas Mc Guire Date: Tue, 10 Feb 2015 03:11:14 -0500 Subject: i2c: designware: fixup return handling of wait_for_completion_timeout return type of wait_for_completion_timeout is unsigned long not int, rather than introducing a new variable the wait_for_completion_timeout is moved into the if condition as the return value is only used to detect timeout.
