sdhci-of: don't hard-code inverted write-protect quirk
has been removed from the -mm tree. Its filename was
sdhci-of-dont-hard-code-inverted-write-protect-quirk.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: sdhci-of: don't hard-code inverted write-protect quirk
From: Anton Vorontsov <avorontsov@xxxxxxxxxxxxx>
MPC85xx SOCs have normal write-protect state reporting, so we shouldn't
hard-code the quirk.
Instead, look for "sdhci,wp-inverted" property, plus check for
mpc837x_{rdb,mds} machines since older device trees don't specify the new
property.
