10ms is only correct with HZ=100. With higher values of HZ you get a
finer resolution. I'd write:

	Respect the transfer timeout set via the I2C_TIMEOUT ioctl.

and not mention the resolution at all. After all your patch doesn't
"enable" that ioctl, just makes use of the value set by it.

Best regards
Uwe
