[ALSA] soc - Don't lock the codec list in snd_soc_dapm_new_widgets() snd_soc_dapm_new_widgets() takes the codec lock when adding new widgets, causing lockdep warnings when applications later call down through ALSA to adjust controls. Since widgets are only added during probe this lock should be unneeded so don't take it. Thanks to Dmitry Baryshkov <[EMAIL PROTECTED]> for reporting this issue.
