Mauro Carvalho Chehab f2dd851ff1 [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.
