When compiling this series I get this error:

drivers/media/i2c/soc_camera/mt9t112.c: In function âmt9t112_init_pllâ:
drivers/media/i2c/soc_camera/mt9t112.c:426:16: error: dereferencing pointer to incomplete type âstruct mt9t112_camera_infoâ
priv->info->divider.m,
^~

Can you take a look?

Regards,

Hans
