Merge tag 'mmc-v4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc
Pull MMC fixes from Ulf Hansson: "A couple of MMC host fixes intended for v4.12 rc3: - sdhci-xenon: Don't free data for phy allocated by devm* - sdhci-iproc: Suppress spurious interrupts - cavium: Fix probing race with regulator - cavium: Prevent crash with incomplete DT - cavium-octeon: Use proper GPIO name for power control - cavium-octeon: Fix interrupt enable code" * tag 'mmc-v4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc: mmc: sdhci-iproc: suppress spurious interrupt with Multiblock read mmc: cavium: Fix probing race with regulator of/platform: Make of_platform_device_destroy globally visible mmc: cavium: Prevent crash with incomplete DT mmc: cavium-octeon: Use proper GPIO name for power control mmc: cavium-octeon: Fix interrupt enable code mmc: sdhci-xenon: kill xenon_clean_phy()
