Keep on setting them (since the strtok() calls have side-effects), but
mark them as unused, since they aren't used afterwards (except in dead
code which should probably go away).
Those warnings go away accordingly:
| CC lnx_acpi.lo
| lnx_acpi.c: In function 'lnxACPIGetEventFromOs':
| lnx_acpi.c:78:8: warning: variable 'GFX' set but not used
[-Wunused-but-set-variable]
| lnx_acpi.c:77:8: warning: variable 'video' set but not used
[-Wunused-but-set-variable]
