I'm working on converting the pca953x driver to using regmap, but since it's not a trivial task I figured I'd post a couple refactoring patches I did so far for 4.9.
The first patch just fixes a couple coding style issues. The second removes a couple unnecessary switches. Last three refactor the read/write_regs functions to avoid if-elses by using function pointers to smaller, specialized routines. Tested with pca9534 and pca9535 chips.
