V4L/DVB (13496): pvrusb2: Support manual extraction of 16KB FX2 firmware
This pvrusb2 change is in support of an existing feature used to help identify and locate newer vendor supplied firmware. This change makes the feature work for the newer larger firmware size. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
