Subject: ASoC: Intel: Show Baytrail SST DSP firmware details during init
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=4131eceb4a5e471f5a866ee10e680f0081376e3b;p=openwrt%2Fstaging%2Fblogic.git

ASoC: Intel: Show Baytrail SST DSP firmware details during init

DSP initialization complete message IPC_IA_FW_INIT_CMPLT is a large message
carrying firmware details in mailbox. Read and show those details during
init in order to be able to get that information to QA reports.
