Subject: media: i2c: imx274: convert to use maple tree register cache
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7591701bdc964b601ccf35797e57f2788a3ce1eb;p=linux.git

media: i2c: imx274: 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.
