X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8c2ebcf103b106bd8b9c5517bf72885d126d3d27;p=linux-beck.git

[media] media: remove obsolete Media Device Managed resource interfaces

Remove obsolete media_device_get_devres(), media_device_find_devres(),
and media_device_release_devres() interfaces. These interfaces are now
obsolete.
