Subject: ALSA: hdac: Fix to read the correct offset of spcap/link register
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a7e3dd85cab1c6990cafd0bedb0b8809f15149b0;p=linux-beck.git

ALSA: hdac: Fix to read the correct offset of spcap/link register

SPCAP and Mutilink register offset were incorrect as offset needs
to be based on capability offset. So correct the offset for
read/write of spcap/link register.
