Subject: [PATCH] arch_init.c: Improve '-soundhw help' for
|
|
|
5544c1 |
non-HAS_AUDIO_CHOICE archs
|
|
|
5544c1 |
|
|
|
5544c1 |
For architectures which don't set HAS_AUDIO_CHOICE, improve the
|
|
|
5544c1 |
'-soundhw help' message so that it doesn't simply print an empty
|
|
|
5544c1 |
list, implying no sound support at all.
