Subject: [PATCH][next] mm: cma: remove redundant null check of the array cma->name

From: Colin Ian King <colin.king@...onical.com>

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")
Signed-off-by: Colin Ian King <colin.king@...onical.com>
