Subject: [PATCH v2 4/6] ASoC: Intel: Skylake: Register dsp_fw_ops for kabylake
Date: Tue, 25 Apr 2017 12:18:22 +0530	[thread overview]
Message-ID: <1493102904-12624-5-git-send-email-subhransu.s.prusty@intel.com> (raw)
In-Reply-To: <1493102904-12624-1-git-send-email-subhransu.s.prusty@intel.com>

For audio kabylake is same as skylake except the module load approach.
This patch registers different dsp_fw_ops for kabylake and next patch
adds the module load support for kabylake.
