Same situation for: [PATCH AUTOSEL 4.18 11/92] mtd: rawnand: sunxi: Add an U suffix to NFC_PAGE_OP definition [PATCH AUTOSEL 4.14 08/57] mtd: rawnand: sunxi: Add an U suffix to NFC_PAGE_OP definition [PATCH AUTOSEL 4.9 04/34] mtd: rawnand: sunxi: Add an U suffix to NFC_PAGE_OP definition [PATCH AUTOSEL 4.4 04/20] mtd: rawnand: sunxi: Add an U suffix to NFC_PAGE_OP definition Thanks, Miquèl
