|
Subject: [PATCH] conf: Allow for a directory to be given as a config file.
|
||||||
|
|
||||||
|
When this is done, *.conf files can be placed in that directory and they
|
||||||
|
will be processed by as if they were included directly.
|
||||||
|
|
||||||
|
A directory (typically /usr/share/alsa/alsa.conf.d/) has been
|
||||||
|
added into the distribution.
|
||||||
|
|
||||||
|
v2: Used existing conf syntax rather than processing via autotools
|
||||||
|
v3: Split file loading into separate function and made error handling
|
||||||
|
more consistent.
