Subject: [PATCH v2] axonram: Delete an unnecessary variable initialisation in
 axon_ram_probe()

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

The local variable "rc" will eventually be set only to an error code.
Thus omit the explicit initialisation at the beginning.

v2:
Three update steps were integrated for this software module on 2017-09-01.
Thus improve another source code place.
