From be951017453cba2f3eb789413f697b8f14393eec Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Mon, 16 Feb 2015 15:25:49 +0000 Subject: [PATCH] ASoC: wm_adsp: Improve round to next 4-byte boundary Whilst the existing code does correctly round to the next 4-byte boundary it does so rather inefficiently. This patch changes the rounding to be simpler and more efficient.
