In 'commit 295ab497d6357 ("[media] media: platform: pxa_camera: make
printk consistent")' a pointer to the device structure in
mclk_get_divisor() was changed to pcdev_to_dev(pcdev). The pointer used
by pcdev_to_dev() is still uninitialized during the call to
mclk_get_divisor() as it happens in v4l2_device_register() at the end
of the probe. The dev_warn and dev_dbg caused a line in the log:
(NULL device *): Limiting master clock to 26000000
Fix this by using an initialized pointer from the platform_device
(as before the old patch).
