[media] fix a warning on avr32 arch
X-Patchwork-Delegate: m.chehab@samsung.com on avr32 arch, those warnings happen: drivers/media/firewire/firedtv-fw.c: In function 'node_update': drivers/media/firewire/firedtv-fw.c:329: warning: comparison is always true due to limited range of data type In this particular case, the signal is desired, as the isochannel var can be initalized with -1 inside the driver. So, change the type to s8, to avoid issues on archs where char is unsigned.
