[ 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]

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.
