Subject: [PATCH 15/35] ASoC: Intel: Skylake: Use dsp loading functions directly
Date: Thu, 22 Aug 2019 21:04:05 +0200	[thread overview]
Message-ID: <20190822190425.23001-16-cezary.rojewski@intel.com> (raw)
In-Reply-To: <20190822190425.23001-1-cezary.rojewski@intel.com>

None of skl_dsp_loader_ops are actually extended as any parameter that
could be "extended" is already part of given function's parameter list.
Rather than obfustace non-derived calls with ops and dereferences, make
use of said operation directly. Takes part in remal of
skl_dsp_loader_ops structure.
