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
