2016-07-14ASoC: Intel: Fix conflicting pcm dev drvdata on haswellBen Zhang
soc-core sets the snd_soc_pcm_runtime->dev drvdata to snd_soc_pcm_runtime in soc_post_component_init, and access it in places like codec_reg_show. hsw_pcm_open overwrites the drvdata to point to hsw_pcm_data, confusing soc-core, and causing crashes when cat /sys/devices/pci0000:00/INT3438:00/.../System PCM/codec_reg This patch removes the set in hsw_pcm_open since it's no longer used. commit 7ff9d6714a5c ("ASoC: Intel: Split hsw_pcm_data for playback and capture") already removed all calls to snd_soc_pcm_get_drvdata(rtd).

2015-06-08ASoC: intel: Remove unused variable hswTakashi Iwai
The recent fix left a variable declaration without usage. sound/soc/intel/haswell/sst-haswell-pcm.c:1349:18: warning: unused variable ‘hsw’ [-Wunused-variable] Fixes: edd8ed496b98 ('ASoC: Intel: handle haswell pcm suspend including runtime modules freeing') Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-06-02ASoC: Intel: handle haswell pcm suspend including runtime modules freeingJie Yang
It needs free pcm runtime modules before unloading firmware, here add hsw_pcm_suspend() to handle this procedure: suspends firmware ==> frees runtime modules ==> unloads firmware. This fixes the broadwell module unload failed issue. Signed-off-by: Jie Yang <yang.jie@intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-06-02ASoC: Intel: check and clear runtime module pointerJie Yang
Add check runtime module pointers before freeing them, and clear them to NULL after freed. With this implemented, we can avoid NULL pointer dereference or double free errors. Signed-off-by: Jie Yang <yang.jie@intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-06-02ASoC: intel: Revert "ASoC: Intel: fix broadwell module removing failed issue"Jie Yang
This reverts commit 01f202c7b4b40025f3ea4721c52e7f78545e3b07. We shouldn't leave the device as suspended state after module freed, it is not good to do runtime suspend at driver free, here revert this fixing, and replace it with the procedure: suspends firmware ==> frees runtime modules ==> unloads firmware.

2015-06-02ASoC: intel: Revert "ASoC: Intel: remove unused function hsw_pcm_free_modules()"Jie Yang
This reverts commit 506c148ee5e1bfb836116353305927ca4c21a23e. We still need this hsw_pcm_free_modules(), we plan to remove the runtime modules at both fw_unload(D0->D3) and snd_soc_sst_haswell_pcm module removing.

2015-05-28ASoC: Intel: fix broadwell module removing failed issueLiam Girdwood
In haswell-pcm module unloading, we can't free runtime modules directly, for they may be already freed in runtime suspend. Here add executing suspend call to unload runtime modules, only for status not equal to RPM_SUSPEND, to fix broadwell module removing failed issue.
