[PATCH v9 3/4] media: media.h: Enable ALSA MEDIA_INTF_T* interface types

From: shuah
Date: Tue Dec 18 2018 - 12:59:52 EST


From: Shuah Khan <shuah@xxxxxxxxxx>

Move PCM_CAPTURE, PCM_PLAYBACK, and CONTROL ALSA MEDIA_INTF_T* interface
types back into __KERNEL__ scope to get ready for adding ALSA support for
these to the media controller.
