Subject: [PATCH] staging: comedi: das1800: prefer kmalloc_array over kmalloc with multiply
Date: Mon, 19 Jan 2015 20:42:49 -0600 [thread overview]
Message-ID: <1421721769-28482-1-git-send-email-chase.southwood@gmail.com> (raw)
Checkpatch doesn't like kmalloc with multiply very much:
drivers/staging/comedi/drivers/das1800.c:1377: WARNING: Prefer kmalloc_array over kmalloc with multiply
So this patch swaps that use out for kmalloc_array instead.
