Subject: [PATCH v2] ivtv-mailbox: avoid confusing smatch
Date: Tue, 23 Feb 2016 07:10:59 -0300	[thread overview]
Message-ID: <dbfb8be944cabea5bc1eef31ca5c93d71f081b41.1456222254.git.mchehab@osg.samsung.com> (raw)

The current logic causes smatch to be confused:
	include/linux/jiffies.h:359:41: error: strange non-value function or array
	include/linux/jiffies.h:361:42: error: strange non-value function or array
	include/linux/jiffies.h:359:41: error: strange non-value function or array
	include/linux/jiffies.h:361:42: error: strange non-value function or array

Use a different logic.
