From 04247e7d65c9ce80a7d19aae2fd7cdf64ce80800 Mon Sep 17 00:00:00 2001 From: Binoy Jayan Date: Wed, 15 Jun 2016 11:00:37 +0530 Subject: [PATCH] staging: wilc1000: Replace semaphore sync_event with completion The semaphore 'sync_event' is used as completion, so convert it to a struct completion type. Also, return -ETIME if the return value of wait_for_completion_timeout is 0.
