Subject: [PATCH] mtd: parser_imagetag: fix error codes in bcm963xx_parse_imagetag_partitions()
Date: Thu, 28 Jan 2021 09:36:52 +0000	[thread overview]
Message-ID: <YBKFtNaFHGYBj+u4@mwanda> (raw)

If the kstrtouint() calls fail, then this should return a negative
error code but it currently returns success.

Fixes: dd84cb022b31 ("mtd: bcm63xxpart: move imagetag parsing to its own parser")
