Date: Fri, 27 May 2016 15:52:58 +0900 From: Daeseok Youn <daeseok.youn@...il.com> To: lidza.louina@...il.com Cc: markh@...pro.net, gregkh@...uxfoundation.org, driverdev-devel@...uxdriverproject.org, devel@...verdev.osuosl.org, linux-kernel@...r.kernel.org, kernel-janitors@...r.kernel.org Subject: [PATCH 1/7] staging: dgnc: remove useless variable 'intr_count' The 'intr_count' variable was used only for increasing. So the 'intr_count' variable is not useful for this driver.
