[PATCH AUTOSEL 5.4 2/7] mmc: core: Respect quirk_max_rate for non-UHS SDIO card

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Shawn Lin <shawn.lin@xxxxxxxxxxxxxx>

[ Upstream commit a2a44f8da29352f76c99c6904ee652911b8dc7dd ]

The card-quirk was added to limit the clock-rate for a card with UHS-mode
support, although let's respect the quirk for non-UHS mode too, to make the
behaviour consistent.
