Subject: [PATCH 0/9] media: uvcvideo: Invert granular PM logic + PM fix

It makes more sense to have a list of the ioctls that need power than
the other way around. This patchset takes care of this.

It also fixes one error in the PM logic introduced in a recent patchset.

To support CI I have included two patches that are in uvc/next but not
in media-committer:
media: uvcvideo: Refactor uvc_queue_streamon
media: uvcvideo: Refactor uvc_v4l2_compat_ioctl32
Do not review them again.

To avoid conflicts I am adding the fop patchset as well:
media: uvcvideo: Use vb2 ioctl and fop helpers
media: uvcvideo: Remove stream->is_streaming field
Please review them in https://patchwork.linuxtv.org/project/linux-media/list/?series=15514
