[alsa-devel] [PATCH alsa-utils 02/11] alsa-info.sh: Read from /proc/modules and sort the result

[David Ward]

Sorting the list of loaded modules makes it much easier to compare
two alsa-info.txt files, even if they are both from the same system
(since the order actually changes after each reboot).

lsmod just formats the contents of /proc/modules. After this script
calls lsmod, it strips everything but module names from the output.
This same result can be obtained just as easily by reading directly
from /proc/modules; then there is no need to remove the header line
printed by lsmod before sorting the output.
