Date: Fri, 03 May 2013 15:16:59 +0900 From: Jingoo Han <jg1.han@...sung.com> To: 'Andrew Morton' <akpm@...ux-foundation.org> Cc: 'LKML' <linux-kernel@...r.kernel.org>, 'Richard Purdie' <rpurdie@...ys.net>, 'Jingoo Han' <jg1.han@...sung.com> Subject: [PATCH 1/4] backlight: atmel-pwm-bl: remove unnecessary platform_set_drvdata() The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound). Thus, it is not needed to manually clear the device driver data to NULL.
