Host endianess does not affect the order that pixel rgb data comes in from the quickcam (the values are bytes, not words or longs). The driver is erroniously swapping the order of rgb values for big endian machines. This patch is needed get the Quickcam communicator working on big endian machines (tested on powerpc) Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
