From bb86124c80780d9d2a2d9bef7f0840e61007ebb7 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 25 Jul 2018 23:00:49 +0200 Subject: [PATCH] ALSA: hda/ca0132 - Use NULL instead of 0 Use NULL for initializing the snd_kcontrol_new.tlv field, instead of 0, as warned by sparse: sound/pci/hda/patch_ca0132.c:5519:22: warning: Using plain integer as NULL pointer Also, the driver does the same initialization twice, once for knew.tlv.c and another for knew.tlv.p while both point to the same address (these are union). Drop the latter superfluous one.
