[PATCH] pinctrl: sx150x: Use maple tree register cache

Posted by Mark Brown 1 year, 4 months ago

The sx150x driver uses a rbtree register cache with no obvious reason for
specifically preferring it. The maple tree register cache is based on a
more modern data structure and makes implementation decisions more suitable
for modern systems so let's switch the driver to use that. No functional
change.
