Merge branch 'fixes' of git://git.linaro.org/people/rmk/linux-arm

Browse source 
Pull ARM fixes from Russell King:
 "This includes three MMCI changes - one to fix up the wrong version of
  the DT support patch which was merged, and two to make deferred
  probing work.  It also includes a fix to the OMAP SPI driver which is
  causing a boot time warning.

  The remainder are very minor ARM fixes."

* 'fixes' of git://git.linaro.org/people/rmk/linux-arm:
  SPI: fix over-eager devm_xxx() conversion
  ARM: 7427/1: mmc: mmci: Defer probe() in case of yet uninitialized GPIOs
  ARM: 7426/1: mmc: mmci: Remove wrong error handling of gpio 0
  ARM: 7425/1: extable: ensure fixup entries are 4-byte aligned
  ARM: 7421/1: bpf_jit: BPF_S_ANC_ALU_XOR_X support
  ARM: 7423/1: kprobes: run t32_simulate_ldr_literal() without insn slot
  ARM: 7422/1: mmc: mmci: Allocate platform memory during Device Tree boot
