From 21e904bcf9b2e57e0599e9dddff558ffd0ce5f59 Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Tue, 9 Jun 2015 14:34:21 +0100 Subject: [PATCH] ASoC: qcom: storm: allocate snd_soc_card struct dynamically. This patch moves static allocation of snd_soc_card to dynamic allocation, the reason to do this is to avoid holding up any dangling pointers in this static structures. And I see no use for having this struct as static given that the card->name is also populated dynamically from dt.
