- * Allocate the MJPEG grab buffers.

- *
- * Ben Capper:
- * On big-endian architectures (such as ppc) some extra steps
- * are needed. When reading and writing to the stat_com array
- * and fragment buffers, the device expects to see little-
- * endian values. The use of cpu_to_le32() and le32_to_cpu()
- * in this function (and one or two others in zoran_device.c)
- * ensure that these values are always stored in little-endian
- * form, regardless of architecture. The zr36057 does Very Bad
- * Things on big endian architectures if the stat_com array
- * and fragment buffers are not little-endian.
