| Subject: [PATCH] V4L: Fix quickcam communicator driver for big endian architectures |
| |
| From: Grant Likely <grant.likely@secretlab.ca> |
| |
| 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) |
| |
| (cherry picked from commit c6d704c8c4453f05717ba88792f70f8babf95268) |
