3.2.80-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Hans de Goede <hdego...@redhat.com> commit 3e71da19f9dc22e39a755d6ae9678661abb66adc upstream. bytesperline should be the bytesperline for the first plane for planar formats, not that of all planes combined. This fixes a crash in xawtv caused by the wrong bpl.
