Subject: [PATCH] mtd: rawnand: Add a check in of_get_nand_secure_regions()
Date: Thu, 17 Jun 2021 16:37:25 +0300	[thread overview]
Message-ID: <YMtQFXE0F1w7mUh+@mwanda> (raw)

Check for whether of_property_count_elems_of_size() returns a negative
error code.

Fixes: 13b89768275d ("mtd: rawnand: Add support for secure regions in NAND memory")
