From 181a68927b9e6ff7c0ea093c2f056eeb0552a911 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 14 Mar 2012 20:18:49 +0000 Subject: [PATCH] ASoC: core: Fix obscure leak of runtime array We're currently not freeing card->rtd in cases where the card is unregistered before being instantiated - convert it to devm_kzalloc() to make sure that happens.
