+Subject: [PATCH] mtd: spinand: esmt: add support for F50L1G41LC
+
+This adds support for ESMT F50L1G41LC, which appears to be an updated
+version of the already supported F50L1G41LB.
+Add esmt_8c SPI_NAND manufacturer to account for the newly used vendor
+ID with support for the ESMT F50L1G41LC chip.
