Subject: media: i2c: max2175: convert to use maple tree register cache
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7378c257db6ae3886c2b300cb62737660dd695a1;p=linux.git

media: i2c: max2175: 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.
