For clearing the reallocated area, we need to clear explicitly instead.

Because the return value is unmodified, the hdac regmap read/write functions should allow this value for the retry I/O operation, too.

These warnings are not the real issues. The patch adds the sanity check.

This calls for a reference counting mechanism on the link by it's users to manage the link power. The DMA can be turned off when all links are off For this we add two APIs snd_hdac_ext_bus_link_get snd_hdac_ext_bus_link_put They help users to turn up/down link and manage the DMA as well Signed-off-by: Jeeja KP <jeeja.kp@intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com> Acked-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Mark Brown <broonie@kernel.org> 2016-05-10T14:06:04+00:00 Takashi Iwai tiwai@suse.de 2016-05-10T14:06:04+00:00 urn:sha1:2e00fde5c6ed8535244332ebb55e881baa54ae46 2016-05-08T09:43:36+00:00 Jeeja KP jeeja.kp@intel.com 2016-05-05T05:54:43+00:00 urn:sha1:38b19ed7f81ec930f3ad2066ae088f574970c814 If the DMAs are not being quiesced properly, it may lead to stability issues, so the recommendation is to wait till DMAs are stopped. After setting the stop bit of RIRB/CORB DMA, we should wait for stop bit to be set.
