To enable the MIDI port, model drivers must now set flags in
device_config, not only in misc_flags.  This allows model drivers to
enable the UART without creating an ALSA MIDI device.

Rename the pcm_dev_cfg field to device_config because there will be

free_irq() calls synchronize_irq() for you, so there is no need for
drivers to manually do the same thing (again).  Thus, calls where
sync-irq immediately precedes free-irq can be simplified.

However, during this audit several bugs were noticed, where free-irq is
preceded by a "irq >= 0" check... but the sync-irq call is not covered
by the same check.

So, where sync-irq could not be eliminated completely, the missing check
was added.
