Merge tag 'pinctrl-v4.3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control fixes from Linus Walleij:
"This is a first set of pin control fixes for the v4.3 series. Nothing
special to say, business as usual.
- Some IS_ERR() fixes from Julia Lawall. I always wanted the
compiler to catch these but error pointers by nailing them as an
err pointer intrinsic type or something seem to be a "no can do".
In any case, cocinelle is obviously up to the task, better than
bugs staying around.
- Better error handling for NULL GPIO chips.
- Fix a compile error from the big irq desc refactoring. I'm
surprised the fallout wasn't bigger than this"
