Merge tag 'mmc-v4.16-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc
Pull MMC fixes from Ulf Hansson:
"A couple of MMC fixes intended for v4.16-rc7:
MMC host:
- dw_mmc: Fix the suspend/resume issue for Exynos5433
- dw_mmc: Fix the DTO/CTO timeout overflow calculation for 32-bit
systems
- dw_mmc: Make PIO mode work when failing with idmac when
dw_mci_reset occurs
- sdhci-acpi: Re-allow IRQ 0 to fix broken probe
MMC core:
- Update EXT_CSD caches to correctly switch partition for ioctl calls
- Fix tracepoint print of blk_addr and blksz
- Disable HPI on broken Micron (Numonyx) eMMC cards"
