From: Doug Anderson Date: Fri, 11 Jan 2013 17:03:54 +0000 (+0000) Subject: mmc: dw_mmc: Remove DW_MCI_QUIRK_NO_WRITE_PROTECT X-Git-Tag: firefly_0821_release~3680^2~1031^2~50 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=9640639b09313af4cd37a465408643aba927808e;p=firefly-linux-kernel-4.4.55.git mmc: dw_mmc: Remove DW_MCI_QUIRK_NO_WRITE_PROTECT The original quirk was added in the change 'mmc: dw_mmc: add quirk to indicate missing write protect line'. The original quirk was added at a controller level even though each slot has its own write protect (so the quirk should be at the slot level). A recent change (mmc: dw_mmc: Add "disable-wp" device tree property) added a slot-level quirk and support for the quirk directly to dw_mmc.
