ata: sata_mv: fix mis-conversion in mv_write_cached_reg()
Fix the signed issue in mv_write_cached_reg() where the laddr is assigned from a (long)addr instead of (unsigned long)addr. Fixes the following warnings: drivers/ata/sata_mv.c:989:26: warning: cast removes address space of expression drivers/ata/sata_mv.c:989:26: warning: cast removes address space of expression drivers/ata/sata_mv.c:989:26: warning: cast removes address space of expression drivers/ata/sata_mv.c:989:26: warning: cast removes address space of expression Signed-off-by: Ben Dooks <ben.dooks@codethink.co.uk> Signed-off-by: Tejun Heo <tj@kernel.org>
