[PATCH 2/2] firewire: endianess annotations

[Stefan Richter <stefanr@s5r6.in-berlin.de>]

Kills warnings from 'make C=1 CHECKFLAGS="-D__CHECK_ENDIAN__" modules':

drivers/firewire/fw-transaction.c:771:10: warning: incorrect type in assignment (different base types)
drivers/firewire/fw-transaction.c:771:10:    expected unsigned int [unsigned] [usertype] <noident>
drivers/firewire/fw-transaction.c:771:10:    got restricted unsigned int [usertype] <noident>
drivers/firewire/fw-transaction.h:93:10: warning: incorrect type in assignment (different base types)
drivers/firewire/fw-transaction.h:93:10:    expected unsigned int [unsigned] [usertype] <noident>
drivers/firewire/fw-transaction.h:93:10:    got restricted unsigned int [usertype] <noident>
drivers/firewire/fw-ohci.c:1490:8: warning: restricted degrades to integer
drivers/firewire/fw-ohci.c:1490:35: warning: restricted degrades to integer
drivers/firewire/fw-ohci.c:1516:5: warning: cast to restricted type
