Don't execute runtime suspend if HDA is not finished initializing. Otherwise, the following errors can occur in hda: snd_hda_intel 0000:00:1b.0: CORB reset timeout#2, CORBRP = 65535 snd_hda_intel 0000:00:1b.0: no codecs initialized Debugged and root-cause found by zhuo-hao.lee@intel.com v2: remove unnecessary extra check for chip init (libin) Signed-off-by: U.
