** that the current GFP_KERNEL|GFP_DMA flags are wrong: firstly we are in
** atomic context, secondly this memory is not used for DMA.
** Also removed some unneeded casts. Thanks to Daniel Drake <dsd@gentoo.org>
+** 2.The Type B Adapter teardown does iounmap on pointers subtracted by a
+** constant offset. Since the offset is in bytes, we need the pointers to
+** be of type void * not uint32_t * so the subtraction is done in the
+** correct units and we iounmap the correct area.
