Merge tag 'PTR_RET-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux

2013-09-05T00:31:11+00:00

Pull PTR_RET() removal patches from Rusty Russell:
 "PTR_RET() is a weird name, and led to some confusing usage.  We ended
  up with PTR_ERR_OR_ZERO(), and replacing or fixing all the usages.

  This has been sitting in linux-next for a whole cycle"

[ There are still some PTR_RET users scattered about, with some of them
  possibly being new, but most of them existing in Rusty's tree too.  We
  have that

      #define PTR_RET(p) PTR_ERR_OR_ZERO(p)

  thing in , so they continue to work for now  - Linus ]

2013-08-28T19:21:42+00:00

In PIO_PUSR and PIO_PPDSR register if a given bit is set 1 this means the
pullup/down for this pin (pin is represented as a bit position) is
disabled.

pinctrl: sh-pfc: remove unnecessary platform_set_drvdata()

2013-08-28T19:14:37+00:00

The driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL.
