From 64d27069755db41daa36e4770d88ebc57617559d Mon Sep 17 00:00:00 2001 From: Dimitris Papastamos Date: Thu, 5 May 2011 14:18:11 +0100 Subject: [PATCH] ASoC: soc-cache: Allow codec->cache_bypass to be used with snd_soc_hw_bulk_write_raw() If we specifically want to write a block of data to the hw bypassing the cache, then allow this to happen inside snd_soc_hw_bulk_write_raw().
