[ Upstream commit 3c27ea23ffb43262da6c64964163895951aaed4e ]
On Linux 5.9-rc1 I get the following warning with apq8016-sbc:
WARNING: CPU: 2 PID: 69 at sound/core/init.c:207 snd_card_new+0x36c/0x3b0 [snd] CPU: 2 PID: 69 Comm: kworker/2:1 Not tainted 5.9.0-rc1 #1 Workqueue: events deferred_probe_work_func pc : snd_card_new+0x36c/0x3b0 [snd] lr : snd_card_new+0xf4/0x3b0 [snd] Call trace: snd_card_new+0x36c/0x3b0 [snd] snd_soc_bind_card+0x340/0x9a0 [snd_soc_core] snd_soc_register_card+0xf4/0x110 [snd_soc_core] devm_snd_soc_register_card+0x44/0xa0 [snd_soc_core] apq8016_sbc_platform_probe+0x11c/0x140 [snd_soc_apq8016_sbc]
This warning was introduced in commit 81033c6b584b ("ALSA: core: Warn on empty module"). It looks like we are supposed to set card->owner to THIS_MODULE.
Fix this for all the qcom ASoC drivers.
