Subject: [PATCH] ALSA: hda: Use maple tree register cache
Git-commit: 15253079ca300160c92c9c0ee2541836463043f6
Patch-mainline: v6.5-rc1
References: jsc#PED-6045 jsc#PED-6036 jsc#PED-6104 jsc#PED-6114 jsc#PED-6067 jsc#PED-6123
HDA can only support single register read and write operations so does not
benefit from block writes. This means it gets no benefit from using the
rbtree register cache over the maple tree register cache so convert it to
use maple trees instead, it is more modern.
