ALSA: oss-mixer - use strlcpy() instead strcpy()
This is mostly a static checker fix more than anything else. We're
copying from a 64 char buffer into a 44 char buffer.
The 64 character buffer is str[] in snd_mixer_oss_build_test_all().
The call tree is:
snd_mixer_oss_build_test_all()
-> snd_mixer_oss_build_test()
-> snd_mixer_oss_build_test().
We never actually do fill str[] buffer all the way to 64 characters.
The longest string is:
sprintf(str, "%s Playback Switch", ptr->name);
ptr->name is a 32 character buffer so 32 plus 16 characters for
" Playback Switch" still puts us over the 44 limit from "id.name".
Most likely ptr->name never gets filled to the limit, but we can't
really change the size of that buffer so lets just use strlcpy() here
and be safe.
