This problem is now causing various runtime failures in mainline.
I see the following qemu test failures:

arm:beagle:multi_v7_defconfig:omap3-beagle
arm:beaglexm:multi_v7_defconfig:omap3-beagle-xm
arm:overo:multi_v7_defconfig:omap3-overo-tobi

I would expect all omap2/3/4/5 runtime tests with multi_v7_defconfig to fail.

Also, FWIW,

Fixes: 6a9b2ff07d04 ("mmc: host: omap_hsmmc: return on fatal errors from omap_hsmmc_reg_get")
