Subject: staging: mt7621-mmc: Remove redundant check for card status
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f71774ac8a4d3e8be9c839386635c519a86995e2;p=linux.git

staging: mt7621-mmc: Remove redundant check for card status

Current code checks the card status at the beginning of
msdc_ops_request. This is not necessary because mmc core always checks
the card status before calling this operation.
