Blackfin arch: rename blackfin_sram.c to sram-alloc.c
rename blackfin_sram.c to sram-alloc.c (we know it is a blackfin file, since it is in arch/blackfin) - and there is no "driver" code in there, it is just an allocator/deallocator for L1 and L2 sram. Also fix a problem that checkpatch pointed out Signed-off-by: Robin Getz <rgetz@blackfin.uclinux.org> Signed-off-by: Bryan Wu <cooloney@kernel.org>
