In this driver there are several entities associated with separate platform or I2C client devices, which may get probed in random order. When the platform device bound to the media device driver is probed all other entity drivers need to be already in place and initialized. If any of them is not, fail the media device probe and return an error indicating we need to be retried once any new driver gets registered. The media device driver probe will not succeed until there are available all needed sub-drivers, as specified in the platform data. While at it, make sure the s5p-csis module (MIPI-CSI receiver driver) does not get unloaded when in use, by guarding its usage with try_module_get/module_put. This patch is a prerequisite for adding the device tree support. It now also allows again to unbind/bind the driver at runtime from user space via sysfs. Signed-off-by:
