Subject: jsm driver fix for linuxpps support
The jsm driver doesn't currently use the uart_handle_*_change helper
functions, which are the obvious place for things like linuxpps to tie
into (which it now does of course), and as a result the jsm driver can
not be used with linuxpps and anything else that ties into the
serial_core helper functions. This patch adds calls to these helper
functions whenever the value they manage changes. That actual storage
of the state is not modified since the jsm driver caches the current
settings (The 8250 driver reads them everytime a user asks for the
state), and only updates them whenever they change.
