[PATCH v2 0/3] gpio: pcf857x: Implement get_multiple/set_multiple methods

[Radu Rendec <radu.rendec@xxxxxxxxx>]

The first two patches are just cosmetic changes. The actual changes are
in the third patch. They are all bundled together in a patch series just
because the third patch doesn't apply cleanly without the other two.

Change description from the third patch:

  This change allows the GPIO core to read/change multiple pins in a
  single driver call and subsequent I2C transfer. It helps a lot with
  PCF857x devices, since their I2C protocol always reads/changes all
  existing pins anyway. Therefore, when the GPIO client code does a bulk
  operation on multiple pins, the driver makes a single I2C transfer.

Radu Rendec (3):
  gpio: pcf857x: Replace 'unsigned' with 'unsigned int'
  gpio: pcf857x: Fix indentation of variable declarations
  gpio: pcf857x: Implement get_multiple/set_multiple methods
