Subject: mm: cma: return cma->name directly in cma_get_name
clang warns:
mm/cma.c:55:14: warning: address of array 'cma->name' will always
evaluate to 'true' [-Wpointer-bool-conversion]
return cma->name ? cma->name : "(undefined)";
~~~~~^~~~ ~
1 warning generated.
After commit e7f0557d7de9 ("mm: cma: fix the name of CMA areas"),
cma->name will be an array with some value worth printing so we do not
need to check for NULL.
