Hi,
this patch adds support for stowaway and stowaway compatible (eg. dicota
inutPDA) serial keyboards. I made it on kernel 2.6.16, but it applies cleanly
on 2.6.17.1 too. I tested it on palm zire71 and friend reported me that it
works on palm tungsten T3.
I appologize, I´m not subscribed to LKML.
Best regards
Marek Vasut
