Noticed that there are plenty of coding style problems in matroxfb_base.h,

why you only fix a few of them?   Take this two line as an example, 
shouldn't

they be fixed also as following?


  	int		(*verifymode)(void *altout_dev, u_int32_t mode);
  	int		(*getqueryctrl)(void *altout_dev,
  					struct v4l2_queryctrl *ctrl);
