The commit  	74f464d2f9f0a5ee6567d1f276c5de4087279e0e

Resolve the dependency more recursively in mod-deps

fix the build of snd-seq-midi.ko and snd-opl3-synth.ko

It work when alsa-driver  is configured with oss kernel emulation

./configure --with-sequencer=yes --with-oss=yes

and fail when alsa-driver is configured without oss

./configure --with-sequencer=yes --with-oss=no

aplaymidi -l
ALSA lib seq_hw.c:457:(snd_seq_hw_open) open /dev/snd/seq failed: No
such file or directory
Cannot open sequencer - No such file or directory

does it mean that 03cfe6f57dc5c13ccdd235c23c80e3fa170f03d1

ALSA: support module on-demand loading for seq and timer

require systemd to load the sequencer

As CONFIG_SND_DYNAMIC_MINORS is used on Kernel 2.6.27 but there is no systemd
