From: Randy Dunlap <[email protected]>

Make iTCO_wdt_probe() be __devinit.
Fixes these section warnings:

WARNING: vmlinux.o(.text+0x17d8a8): Section mismatch: reference to .init.data: (between 'iTCO_wdt_probe' and 'supermicro_new_unlock_watchdog')
WARNING: vmlinux.o(.text+0x17d97e): Section mismatch: reference to .init.data: (between 'iTCO_wdt_probe' and 'supermicro_new_unlock_watchdog')
WARNING: vmlinux.o(.text+0x17d989): Section mismatch: reference to .init.data:iTCO_chipset_info (between 'iTCO_wdt_probe' and 'supermicro_new_unlock_watchdog')
