From b1470d4ce77c2d60661c7d5325d4fb8063e15ff8 Mon Sep 17 00:00:00 2001 From: Ajit Pandey Date: Tue, 7 Aug 2018 18:30:42 +0100 Subject: [PATCH] ASoC: wm_adsp: Correct DSP pointer for preloader control The offset of the DSP core needs to be taken into account for the DSP preloader control get and put. Currently the dsp->preloaded variable will only ever be read/updated on the first DSP, whilst this doesn't affect the operation of the control the readback will be incorrect.
