Subject: [PATCH 0/4] leds: Convert to use maple tree register cache

The maple tree register cache is a more modern replacement for the
rbtree cache, the underlying data structure is more modern and the
surrounding cache implementation makes a number of choices which are
more suited to modern systems than those made by rbtree. This series
updates the LED drivers that use the rbtree cache to use the maple tree
cache.

Subject: [PATCH 3/4] leds: lm392x: Convert to use maple tree register cache

The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache.
