Subject: mmc: tmio: check mmc_regulator_get_supply return value
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).
