From 569ef65a973e19ec3327c8efbcf26bfc844af7e3 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Tue, 28 May 2013 19:22:12 +0200 Subject: [PATCH] ASoC: blackfin: bf5xx-i2s: Allocate buffer only as large as requested There is no need to always allocate the maximum buffer size. While we are at it also pass errors returned by snd_pcm_lib_malloc_pages() on to the upper layers.
