- * set the @align and @size values in struct video_uc_platdata. This
+ * set the @align and @size values in struct video_uc_plat. This
* information represents the requires size and alignment of the frame buffer
* for the device. The values can be an over-estimate but cannot be too
* small. The actual values will be suppled (in the same manner) by the bind()
- * method after relocation.
+ * method after relocation. Additionally driver can allocate frame buffer
+ * itself by setting plat->base.
*
* This information is then picked up by video_reserve() which works out how
* much memory is needed for all devices. This is allocated between
