[PATCH 1/2] audio: Replace g_hash_table_contains() with g_hash_table_lookup()

[PATCH 1/2] audio: Replace g_hash_table_contains() with g_hash_table_lookup()

[Jaganath Kanakkassery]

g_hash_table_contains() is supported only from GLib 2.32. If BlueZ has to
build against GLib 2.28 this patch replaces g_hash_table_contains() to
g_hash_table_lookup()

I changed this into unsigned int instead when applying the patch.

Doesn't

return g_hash_table_lookup(mp->settings, property->name) != NULL;

do the same? Maybe it's againist some code style but looks better
than several lines.

I think
return g_hash_table_lookup(mp->settings, property->name) ? TRUE : FALSE;
would be better?

Shorter form is  != NULL, so lets go with it, still haven't figure out
why we didn't bring back glib-compat for such functions, when we
finally upgrade it will take much more time to revert this one by one.

we could bring glib-compat back, but right now I do not want to
introduce more autoconf magic to do so.

I would require the latest GLib version (or at least a bit newer one) if
they wouldn't just start introducing new dependencies all the time.
