2.5.14 OSS emulation

2.5.14 OSS emulation

[Pierre Rousselet]

 From ChangeLog-2.5.14 :

<hch@infradead.org> (02/05/05 1.545)
	[PATCH] fix config.in syntax errors.
        - sound uses a bool where it should use a dep_bool

This prevents using OSS emulation with ALSA drivers. What is the reason 
behind ?

2.4.13 used to do (in sound/core/Config.in):

bool '  OSS API emulation' CONFIG_SND_OSSEMUL $CONFIG_SND

The bool verb take exaxctly two arguments, the option description
and the config option itself, if you want additional depencies you
have to use dep_bool instead.

If this fix breaks ALSA it only shows that it has even deeper config
problems - I don't use ALSA and care only about the syntactical
correctness of that file.

The correct fix should be:

bool '  OSS API emulation' CONFIG_SND_OSSEMUL

I'm sorry about that.

This is very true.  I've had trouble getting my YMFPCI sound to work 
with ALSA probably for this reason: bad configs.  (After all, I was told 
the YMFPCI code is the same for OSS and ALSA).
