Subject: [PATCH 2/3] rapidio: tsi721_dma: Delete an unnecessary variable
 initialisation in tsi721_alloc_chan_resources()

From: Markus Elfring <elfring@...rs.sourceforge.net>

The local variable "desc" will eventually be set to an appropriate pointer
a bit later. Thus omit the explicit initialisation at the beginning.
