stable inclusion from stable-v6.6.9 commit ff02d91704fad1a58b145ff4625066f5726aa0ac bugzilla: https://gitee.com/openeuler/kernel/issues/I99TJK
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit ec1de5c214eb5a892fdb7c450748249d5e2840f5 upstream.
Currently, cur_prog/cur_conf remains at the default value (-1), while program 0 has been loaded into the amplifiers.
In the playback hook, tasdevice_tuning_switch tries to restore the cur_prog/cur_conf. In the runtime_resume/system_resume, tasdevice_prmg_load tries to load the cur_prog as well.
Set cur_prog and cur_conf to 0 if available in the firmware.
