From 20a24225d8f94fc56f74a9068684869d6deebea5 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 29 May 2013 12:37:32 +0200 Subject: ALSA: PCI: Remove superfluous pci_set_drvdata(pci, NULL) at remove As drvdata is cleared to NULL at probe failure or at removal by the driver core, we don't have to call pci_set_drvdata(pci, NULL) any longer in each driver. The only remaining pci_set_drvdata(NULL) is in azx_firmware_cb() in hda_intel.c. Since this function itself releases the card instance, we need to clear drvdata here as well, so that it won't be released doubly in the remove callback.
