Message-Id: <1430488699-10878-1-git-send-email-christophe.jaillet@wanadoo.fr> Date: Fri, 1 May 2015 15:58:19 +0200 From: Christophe Jaillet <christophe.jaillet@...adoo.fr> To: starvik@...s.com, jesper.nilsson@...s.com Cc: linux-cris-kernel@...s.com, linux-kernel@...r.kernel.org, kernel-janitors@...r.kernel.org, Christophe Jaillet <christophe.jaillet@...adoo.fr> Subject: [PATCH] cris: arch-v32: gpio: Use kzalloc instead of kmalloc/memset Turn a kmalloc/memset into an equivalent kzalloc. Doing so also move the zero'ing of the memory outside of a mutex.
