While at it you should call v4l2_fh_exit() in the isp_video_release() function 
as well. I propose updating the commit message to

    v4l: omap3isp: Clean up file handle in open() and release()
    
    Both functions initialize the file handle with v4l2_fh_init() and thus
    need to call clean up with v4l2_fh_exit() as appropriate. Fix it.

Same comment for the OMAP4 ISS patches you've submitted.
