Subject[PATCH 7/8] mmc-core: Use kcalloc() in mmc_test_alloc_mem()
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 8 Jan 2017 21:43:12 +0100

* The script "checkpatch.pl" pointed information out like the following.

WARNING: Prefer kcalloc over kzalloc with multiply

Thus fix the affected source code place.

* Replace the specification of a data structure by a pointer dereference
to make the corresponding size determination a bit safer according to
the Linux coding style convention.
