There are three improvements: a) Use a already initialized device as first
parameter to dev_err() and b) indicate that the error will be ignored, and
c) downgrade to a warning.
This changes the error message from
ERROR: <NULL>: Failed to get 'vmmc' regulator.
to
WARNING: bcm2835_mci fe340000.mmc@xxxxxxxxxxx: Failed to get 'vmmc' regulator (ignored).
