Subject: [PATCH net-next 1/2] net: macvtap: fix template string argument of device_create() call

From: Jean Sacren <sakiwit@...il.com>

The last argument of device_create() call should be a template string.
The tap_name variable should be the argument to the string, but not the
argument of the call itself.  We should add the template string and turn
tap_name into its argument.
