* Merge from debian alsa-driver svn, remaining changes:
- Script paths (/usr/sbin -> /sbin, /usr/bin -> /bin);
- debian/rules:
+ Don't install snddevices and program-wrapper
+ install alsa-base apport hook
+ Package separate USB card list file
- Vcs and maintainer fields mangling
- Rename blacklist files in /etc/modprobe.d to be consistant with the rest
of the distro
- debian/alsa-base.init:
+ create /var/run/alsa if it doesn't exist
+ Run alsactl store before force unloading modules
+ Run alsactl restore after reloading unloaded modules
- debian/linux-sound-base.postrm: Remove /etc/modprobe.d/blacklist* files
on package removal
- Add missing $CMDLINE_OPTS to all install rules.
- Replace -Q with --quiet.
- Add --use-blacklist to all rules so the blacklist still takes effect.
- debian/alsa-base.postinst: Do not run snddevices
- retain patches:
+ add_suspend_quirk_hp_nc6220_nw8240.patch,
+ refix_lp_68659_by_disabling_dxs_for_0x1458a002.patch.
- Drop kernel-package recommends to a suggests in order to be able to demote
kernel-package to universe
- Script paths (/usr/sbin -> /sbin, /usr/bin -> /bin);
