Subject: [PATCH v2 0/5] gpio: pca953x: code refactoring

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.

v1 -> v2:
- constified the offset structures in patch 2/5

Bartosz Golaszewski (5):
  gpio: pca953x: coding style fixes
  gpio: pca953x: code shrink
  gpio: pca953x: refactor pca953x_write_regs()
  gpio: pca953x: remove an unused variable
  gpio: pca953x: refactor pca953x_read_regs()
