+Subject: [PATCH 45/49] mtd: cafe_nand: fix an & vs | mistake
+
+commit 48f8b641297df49021093763a3271119a84990a2 upstream.
+
+The intent here was clearly to set result to true if the 0x40000000 flag
+was set.  But instead there was a | vs & typo and we always set result
+to true.
+
+Artem: check the spec at
+wiki.laptop.org/images/5/5c/88ALP01_Datasheet_July_2007.pdf
+and this fix looks correct.
