ieee1934: dv1394: interrupt enabling/disabling broken on big-endian
After annotating the frame structs, this was left:
drivers/ieee1394/dv1394.c:2113:23: warning: invalid assignment: |=
drivers/ieee1394/dv1394.c:2113:23: left side has type restricted __le32
drivers/ieee1394/dv1394.c:2113:23: right side has type int
drivers/ieee1394/dv1394.c:2121:24: warning: invalid assignment: &=
drivers/ieee1394/dv1394.c:2121:24: left side has type restricted __le32
drivers/ieee1394/dv1394.c:2121:24: right side has type int
drivers/ieee1394/dv1394.c:2123:24: warning: invalid assignment: |=
drivers/ieee1394/dv1394.c:2123:24: left side has type restricted __le32
drivers/ieee1394/dv1394.c:2123:24: right side has type int
Which looks like a real bug on a big-endian arch as it would set/clear
the wrong bit.

I finally got a chance to test the patch on my kernel, and live DV
viewing using xine still worked fine. Although I admit to being
mystified how it works both before and after the patch, since the
cpu_to_le32() calls that were added should result in byte swapping on
PPC that wasn't being done before. I guess that either the code paths
involved aren't actually being triggered by my xine DV viewing, or
there's some fortuitous palindromic setting of bits.
