Subject: [PATCH] ARM: plat-pxa: Use kmalloc_array() in pxa_dma_init_debugfs()
Date: Wed, 24 Aug 2016 17:57:27 +0200 [thread overview]
Message-ID: <b10c8b2d-1cc7-1d81-3205-d84621791684@users.sourceforge.net> (raw)
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 24 Aug 2016 17:45:51 +0200
A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus reuse the corresponding function "kmalloc_array".
This issue was detected by using the Coccinelle software.
