Subject: [PATCH 7/9] ARM: OMAP2+: Use kcalloc() in sr_set_nvalues()
Date: Sat, 3 Jun 2017 20:33:10 +0200	[thread overview]
Message-ID: <201e94ac-bbd7-5fb0-582b-4a6b2585bdab@users.sourceforge.net> (raw)
In-Reply-To: <e9d44aa5-9208-9ff3-46ec-cd58ac3f4696@users.sourceforge.net>

* A multiplication for the size determination of a memory allocation
  indicated that an array data structure should be processed.
  Thus use the corresponding function "kcalloc".

  This issue was detected by using the Coccinelle software.

* 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.
