Subject: [PATCH] mailbox: imx: Fix an IS_ERR() vs NULL bug
Date: Wed, 24 Nov 2021 17:51:26 +0300	[thread overview]
Message-ID: <20211124145126.GC13656@kili> (raw)

The devm_kzalloc() function does not return error pointers, it returns
NULL on failure.

Fixes: 97961f78e8bc ("mailbox: imx: support i.MX8ULP S4 MU")
