From 0d6821040034b8bfc9d9a4e6c2236f3a9e02650f Mon Sep 17 00:00:00 2001 From: Dharageswari R Date: Fri, 8 Jul 2016 18:15:03 +0530 Subject: ASoC: Intel: Skylake: Fix to use the actual size for TLV control DSP expects the actual length of parameters that is set through TLV to be passed in large config set, so pass the actual size received in tlv_control_set() instead of max size.
