Subject: mmc: remove the call to check_disk_change
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9eb994ec54be320b51fba48d1e52a046cbb742a5;p=linux.git

mmc: remove the call to check_disk_change

The mmc driver doesn't support event notifications, which means
that check_disk_change is a no-op.
