[PATCH] mmc: Change the enhanced area related sysfs output format

From: Beata Baranowska
Date: Tue Jun 14 2016 - 04:49:06 EST


From: Chuanxiao Dong <chuanxiao.dong@xxxxxxxxx>

When the enhanced area feature was not enabled, the related sysfs will
have -EINVAL(-22) value, so change the sysfs output format to display
the correct value.
