From bab4445f9a083f087d0ebb4ba3e9dde669a6b9a5 Mon Sep 17 00:00:00 2001 From: Vinod Koul Date: Wed, 17 Jun 2015 11:20:17 +0530 Subject: ALSA: hda: add hda link cleanup routine In HDA extended bus the HDA link objects are created when multilink capabilities are parsed. We need a routine which free up these link objects for a bus. So add snd_hdac_link_free_all routine Signed-off-by: Jeeja KP Signed-off-by: Vinod Koul Signed-off-by: Takashi Iwai --- sound/hda/ext/hdac_ext_controller.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) (limited to 'sound') diff --git a/sound/hda/ext/hdac_ext_controller.c b/sound/hda/ext/hdac_ext_controller.c index adffc89541c9..b2da19b60f4e 100644 --- a/sound/hda/ext/hdac_ext_controller.c +++ b/sound/hda/ext/hdac_ext_controller.c @@ -193,6 +193,24 @@ int snd_hdac_ext_bus_get_ml_capabilities(struct hdac_ext_bus *ebus) } EXPORT_SYMBOL_GPL(snd_hdac_ext_bus_get_ml_capabilities); +/** + * snd_hdac_link_free_all- free hdac extended link objects + * + * @ebus: HD-audio ext core bus + */ + +void snd_hdac_link_free_all(struct hdac_ext_bus *ebus) +{ + struct hdac_ext_link *l; + + while (!list_empty(&ebus->hlink_list)) { + l = list_first_entry(&ebus->hlink_list, struct hdac_ext_link, list); + list_del(&l->list); + kfree(l); + } +} +EXPORT_SYMBOL_GPL(snd_hdac_link_free_all); + /** * snd_hdac_ext_bus_get_link_index - get link based on codec name * @ebus: HD-audio extended core bus -- cgit
