ACK/Cmnt: [PATCH v1 0/1] [SRU][J:linux-bluefield][PATCH v1 1/1] UBUNTU: SAUCE: mmc: sdhci-of-dwcmshc: Add runtime PM operations for BlueField-3

[Bartlomiej Zolnierkiewicz]

Acked-by: Bartlomiej Zolnierkiewicz <bartlomiej.zolnierkiewicz at canonical.com>

Using module parameters interface instead of custom sysfs entries for
passing information to user-space looks a bit strange to me but it
doesn't seem to cause problems.

Also please use the shortened URL for BugLink (in case of this
submission it should be https://bugs.launchpad.net/bugs/2015307) next
time (I can correct this while applying the patch so there is no need
to resubmit it).

Best regards,
