[PATCH 5.15 039/484] ARM: pxa: spitz: use gpio descriptors for audio
5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann arnd@arndb.de
[ Upstream commit 726d8c965bae2d7468445d990849e281dca8cbf7 ]
The audio driver should not use a hardwired gpio number from the header. Change it to use a lookup table.
