But what does this fix? That's only a
warning, the driver itself doesn't care
at all. The fix you propose, will need
more testing, at least a confirmation
from the reporter. I simply thought this
can't happen. Now you say its a perfectly
sane situation, and then there is nothing
to care about, just shut up the warning.
No?
