Subject: HTC Dream camera, not need sizeof

  On line 258,  sizeof(extlen), always will be sizeof( unit32_t) or 4  

  It seems that something is wrong?!?!  :)


Original 

 255    extlen = sizeof(struct vfe_frame_extra);
 256
 257        extdata =
 258                kmalloc(sizeof(extlen), GFP_ATOMIC);

is equal         kmalloc(sizeof(uint32_t), GFP_ATOMIC);
But then do not need to calculate the size of the structure - 
sizeof(vfe_frame_extra) ???

 259        if (!extdata) {
 260                rc = -ENOMEM;
 261                goto init_fail;

---------------------
May be next?
