Hi David,

The flags argument that serio_interrupt() accepts not the raw protocol
data, but sanitized, protocol-independent SERIO_TIMEOUT, SERIO_PARITY
and SERIO_FRAME bits.

Thanks.

Hi Dmitry,

I've updated the patch so that the raw protocol is converted to the 
SERIO_ bits. The raw protocol can parse only one flag, so I don't need 
to store multiple SERIO_ bits in the character flag variable.

Thanks
- David

Hi Dmitry,

is my last patch okay for you? Just want to know if I can give you 
further help on this and if it is planned to integrate my patch.

Thanks

Hi David,

The patch should hit mainline real soon now, no action is needed on your

Thanks.
