Subject: staging: comedi: das1800: prefer kmalloc_array over kmalloc with multiply
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bff776931e6589192f07f22e1ec17b8eb878bd1a;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

staging: comedi: das1800: prefer kmalloc_array over kmalloc with multiply

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.
