Subject: ASoC: amd: acp: acp63: Use AMD_NODE
X-Git-Tag: v6.15-rc1~173^2~4^2~104^2~3
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8f969537149d672d40a0e75a83f39451a5402780;p=thirdparty%2Fkernel%2Flinux.git

ASoC: amd: acp: acp63: Use AMD_NODE

All consumers of SMN in the kernel should be doing it through the
functions provided by AMD_NODE.

Stop using the local SMN read/write symbols and switch to the AMD_NODE
provided ones.
