* SOC_CAMERA is only enabled on 3.4 as it depends on some
|
|
* newer regulator functionality, however there are some SOC
|
|
* cameras that can rely on the 3.3 regulatory built-in core
|
|
* and the 3.3 SOC_CAMERA module however two routines are
|
|
* not exported in that version of SOC_CAMERA that newer
|
|
* SOC cameras do require. Backport that functionality.
|
|
*
|
|
* Technically this should go into <media/soc_camera.h>
|
|
* given that is where its where its exported on linux-next
|
|
* but in practice only placing it here actually fixes linking
|
|
* errors for 3.3 for all SOC camera drivers we make available
|
|
* for 3.3.
