+Subject: [PATCH] mtd: parsers: ofpart: make symbol 'bcm4908_partitions_quirks'
+ static
+
+The sparse tool complains as follows:
+
+drivers/mtd/parsers/ofpart_core.c:25:32: warning:
+ symbol 'bcm4908_partitions_quirks' was not declared. Should it be static?
+
+This symbol is not used outside of ofpart_core.c, so this
+commit marks it static.
+
+Fixes: 457da931b608 ("mtd: parsers: ofpart: support BCM4908 fixed partitions")

++description: |
++  Linksys devices based on Broadcom Northstar architecture often use two
++  firmware partitions. One is used for regular booting, the other is treated as
++  fallback.
++
++  This binding allows defining all fixed partitions and marking those containing
++  firmware. System can use that information e.g. for booting or flashing
++  purposes.
