Subject: sdhci: reduce card detection delay
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=04cf585d2902404ed06861c6dc27897100340dba;p=linux.git

sdhci: reduce card detection delay

The card detection delay was added early when the behaviour of the
card interrupt was still very much unknown (i.e. before there was a
public specification). As it is now known that it is a debounced signal,
reduce the delay to something more sensible.
