Subject: [PATCH 1/2] [media] dvb-tc90522: Use kmalloc_array() in
tc90522_master_xfer()
From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 7 Oct 2016 21:07:43 +0200
A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "kmalloc_array".
This issue was detected by using the Coccinelle software.
