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.
