From a3bb8f3f818667872728085497b3a3ab3caba371 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 29 Dec 2011 17:51:20 +0100 Subject: [PATCH] ASoC: davinci-vcif.c: use devm_ functions The various devm_ functions allocate memory that is released when a driver detaches. This patch uses devm_kzalloc, devm_request_mem_region and devm_ioremap for data that is allocated in the probe function of a platform device and is only freed in the remove function.
