Are you talking about the following line?
+ else
+ hid_mousepoll_interval = interval;
If so, I put it there, to fill a tiny gap, i felt was missing.
If no parameter is passed, hid_mousepoll_interval is obviously 0.
If a user, who doesn't pass the parameter to usbhid, reads
'/sys/module/usbhid/parameters/mousepoll', the answer would be "0",
which is incorrect, no?
Thanks,
Mikkel
