Subject: [PATCH 1/4] ASoC: Intel: sst: load firmware using async callback
Date: Thu, 30 Oct 2014 16:20:56 +0530 [thread overview]
Message-ID: <1414666259-4450-2-git-send-email-vinod.koul@intel.com> (raw)
In-Reply-To: <1414666259-4450-1-git-send-email-vinod.koul@intel.com>
We would like the DSP firmware to be available in driver as soon as possible. So
use the async callback in driver to probe to load the firmware as soon as
usermode is up
