X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=728f337477a7559e1f6316d8d32394cbd4084689;p=linux.git

mfd: max77686: 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.
