[PATCH 4.4 087/192] [PATCH 091/135] mmc: sdhci: Do not BUG on invalid vdd

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 9d5de93f6d543b356e39e225988ef443a7bce34c ]

The driver may not be able to set the power correctly but that
is not a reason to BUG().
