When compiling this series I get this error:

drivers/media/i2c/soc_camera/mt9t112.c: In function ‘mt9t112_init_pll’:
drivers/media/i2c/soc_camera/mt9t112.c:426:16: error: dereferencing pointer to incomplete type ‘struct mt9t112_camera_info’
      priv->info->divider.m,
                ^~

Can you take a look?

Regards,

	Hans
