Subject: mm/cma: remove stray newline from auto-generated CMA area name
Date: Mon, 10 Aug 2026 17:32:15 +0800

When no name is supplied, cma_new_area() generates names with format
"cma%d\n", introducing an unintended newline character ('\n') in the CMA
name.

Most CMA regions are created with explicit names, so this path is seldom
hit.  The newline only creates cosmetic noise in debug logs, traces and
debugfs with no functional impact.
