   4 Subject: [PATCH] mmc: quirks: add MMC_QUIRK_BROKEN_ERASE for Phison/Integral
   5  cards
   6
   7 Recent Integral cards end up with corrupt sectors after a flash erase.
   8 This covers sizes for the A2 range, which can't be differentiated from
   9 the A1 range which might not have the same issue.
