6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tomi Valkeinen tomi.valkeinen@ideasonboard.com
commit 42d0ec194aa12e9b97f09a94fe565ba2e5f631a2 upstream.
UB9702 does not have SP and EQ registers, but the driver uses them in log_status(). Fix this by separating the SP and EQ related log_status() work into a separate function (for clarity) and calling that function only for UB960.
