[media] gspca - main: rename build_ep_tb to build_isoc_ep_tb
After the "gspca: Fix bulk mode cameras no longer working (regression fix)" patch build_ep_tb is no longer being called for bulk endpoints. This patch renames build_ep_tb to build_isoc_ep_tb to make clear it should only be called for isoc mode cameras. This patch also: - drops the no longer needed xfer parameter - removes a check for bulk mode from the build_isoc_ep_tb code Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jean-François Moine <moinejf@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
