6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Richard Fitzgerald rf@opensource.cirrus.com
[ Upstream commit f6c967941c5d6fa526fdd64733a8d86bf2bfab31 ]
Put the silicon revision and secured flag in the wm_adsp fwf_name string instead of including them in the part string.
This changes the format of the firmware name string from
cs35l56[s]-rev-misc[-system_name]
to cs35l56-rev[-s]-misc[-system_name]
No firmware files have been published, so this doesn't cause a compatibility break.
Silicon revision and secured flag are included in the firmware filename to pick a firmware compatible with the part. These strings were being added to the part string, but that is a misuse of the string. The correct place for these is the fwf_name string, which is specifically intended to select between multiple firmware files for the same part.
Backport note: This won't apply to kernels older than v6.6.
