Subject: [PATCH 5/7] staging: wilc1000: Replace semaphore close_exit_sync with completion
Date: Mon, 13 Jun 2016 16:07:37 +0530	[thread overview]
Message-ID: <1465814259-3009-6-git-send-email-binoy.jayan@linaro.org> (raw)
In-Reply-To: <1465814259-3009-1-git-send-email-binoy.jayan@linaro.org>

The semaphore 'close_exit_sync' is used as completion, so convert
it to a struct completion type.
