Subject[PATCH 3/5] IB/hfi1: Adjust another size determination in hfi1_user_sdma_alloc_queues()
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 10 Feb 2017 08:50:45 +0100

* Pass a product for a call of the function "vmalloc_user" without storing
it in an intermediate variable.

* Delete the local variable "memsize" which became unnecessary with
this refactoring.
