[ALSA] dynamic minors (5/6): reduce maximum number of MIDI devices per card
Modules: ALSA sequencer,Generic drivers To allow increasing the maximum number of sound cards, we have to limit the number of sequencer clients per card because client numbers are still allocated statically. Reducing the number of clients to four limits the number of sequencer MIDI ports to 1024 per card. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
