[PATCH 65/70] xen-netback: remove redundent parameter in netbk_count_requests

From: Luis Henriques
Date: Tue Jun 04 2013 - 10:10:39 EST


3.5.7.14 -stable review patch. If anyone has any objections, please let me know.

------------------

From: Wei Liu <wei.liu2@xxxxxxxxxx>

commit ac69c26e7accb04ae2cb9ab0872068983a42b3c8 upstream.

Tracking down from the caller, first_idx is always equal to vif->tx.req_cons.
Remove it to avoid confusion.
