Could you please help to provide more details on how are you expecting the
split of the patches?
Do you expect to split V4L2 ctrls_init/s_ctrl/g_ctrl in one patch and the
introduction of all the capabilities into another patch? We are not finding
it feasible to split the patch that way as in ctrl_init we read the
capability from platform data to initialize the respective control.
