Su Hui abbd28d04c ALSA: ac97: Fix possible error value of *rac97 ... [ Upstream commit 67de40c9df ] Before committing 79597c8bf6, *rac97 always be NULL if there is an error. When error happens, make sure *rac97 is NULL is safer. For examble, in snd_vortex_mixer(): err = snd_ac97_mixer(pbus, &ac97, &vortex->codec); vortex->isquad = ((vortex->codec == NULL) ? 0 : (vortex->codec->ext_id&0x80)); If error happened but vortex->codec isn't NULL, this may cause some problems. Move the judgement order to be clearer and better.
