Subject: [PATCH v2 02/15] nand: Don't dereference NULL manufacturer_desc
Date: Sat,  4 Nov 2023 16:37:40 -0400	[thread overview]
Message-ID: <20231104203753.1579217-3-seanga2@gmail.com> (raw)
In-Reply-To: <20231104203753.1579217-1-seanga2@gmail.com>

When no manufacturer is matched, manufacturer_desc is NULL. Avoid
dereferencing it in that case.

Fixes: 4e67c571252 ("mtd,ubi,ubifs: sync with linux v3.15")
