Subject: USB: Remove unneeded pointer intf from speedtch_upload_firmware()
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=011db815231f40d4d53531b5d41b82c8dc7c44bf;p=deliverable%2Flinux.git

USB: Remove unneeded pointer intf from speedtch_upload_firmware()

This trivial patch removes the unneeded pointer intf returned from
usb_ifnum_to_if(), which is never used. The check for NULL can be simply done
by if (!usb_ifnum_to_if(usb_dev, 2)).
