[ALSA] dynamic minors (6/6): increase maximum number of sound cards
Modules: ALSA Core,Memalloc module,ALSA sequencer With dynamic minor numbers, we can increase the number of sound cards. This requires that the sequencer client numbers of some kernel drivers are allocated dynamically, too. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
