Subject: mmc: dw_mmc: Run card detect tasklet during slot initialisation.
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=dd6c4b9807581b37bf68ba3cd160c6859f070d39;p=deliverable%2Flinux.git

mmc: dw_mmc: Run card detect tasklet during slot initialisation.

We need to run the card detect tasklet at the end of slot initialisation
as it is possible that a card has been inserted prior to boot, so we don't
see an insertion interrupt and now the card is sitting there inserted but
with no power to it.
