From 38e2a644174e74f948ec4415ae5b5c76f1412b0e Mon Sep 17 00:00:00 2001 From: Nicholas Mc Guire Date: Thu, 8 Jan 2015 13:27:34 +0100 Subject: [PATCH] ath10k: fixup wait_for_completion_timeout return handling wait_for_completion_timeout does not return negative values so the tests for <= 0 are not needed and the case differentiation in the error handling path unnecessary.
