[PATCH] net-i40e: Replace variable initialisations by assignments in i40e_vc_get_vf_resources_msg()

Show all headers | View raw

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 1 Jan 2016 15:11:09 +0100

Replace explicit initialisations for four local variables at the beginning
by assignments that will only be performed if the corresponding code
will really be executed.
