[PATCH] : Sound module locking - uart401

[Chris Rankin]

Hi,
I was going to save this patch until people (Alan) returned from
linux.conf.au, but seeing as 2.4.0-ac10 has just been posted ...

This patch makes the uart401 honour the module owner for MIDI and
synth devices, and then moves the MIDI operations into the text
section.

Chris
