From: Fabrizio Castro fabrizio.castro@bp.renesas.com
[ Upstream commit a3d95d1d4007b1fefd6d8b12db26fda05de05cfb ]
mmc_regulator_get_supply returns -EPROBE_DEFER if either vmmc or vqmmc regulators had their probing deferred. vqmmc regulator is needed by UHS to work properly, therefore this patch checks the value returned by mmc_regulator_get_supply to make sure we have a reference to both vmmc and vqmmc (if found in the DT).
