1From: Prasad J Pandit <address@hidden>

3When IDE AHCI emulation uses Frame Information Structures(FIS)
4engine for data transfer, the mapped FIS buffer address is stored
5in a static 'bounce.buffer'. When a request is made to map another
6memory region, address_space_map() returns NULL because
7'bounce.buffer' is in_use. It leads to a null pointer dereference
8error while doing 'dma_memory_unmap'. Add a check to avoid it.
