Message-Id: <1354831840-21623-1-git-send-email-Julia.Lawall@lip6.fr> Date: Thu, 6 Dec 2012 23:10:40 +0100 From: Julia Lawall <Julia.Lawall@...6.fr> To: Lauro Ramos Venancio <lauro.venancio@...nbossa.org> Cc: kernel-janitors@...r.kernel.org, Aloisio Almeida Jr <aloisio.almeida@...nbossa.org>, Samuel Ortiz <sameo@...ux.intel.com>, linux-wireless@...r.kernel.org, linux-nfc@...ts.01.org, linux-kernel@...r.kernel.org Subject: [PATCH] drivers/nfc/nfcwilink.c: use devm_kzalloc From: Julia Lawall <Julia.Lawall@...6.fr> devm_kzalloc allocates memory that is released when a driver detaches. This patch uses devm_kzalloc for data that is allocated in the probe function of a platform device and is only freed in the remove function.
