Subject: [PATCH][next] mm: cma: remove redundant null check of the array cma->name
Date: Mon, 22 Jun 2020 14:48:50 +0000	[thread overview]
Message-ID: <> (raw)

From: Colin Ian King <>

An earlier commit changed name from a pointer to an array so the
cma->name null check is now redundant and can be removed.

Addresses-Coverity: ("Array compared against 0")
Fixes: e7f0557d7de9 ("mm: cma: fix the name of CMA areas")
