Running sparse (make C=1) on tsa.c raises a lot of warning such as:
--- 8< ---
warning: incorrect type in assignment (different address spaces)
expected void *[noderef] si_regs
got void [noderef] __iomem *
--- 8< ---
Indeed, some variable were declared 'type *__iomem var' instead of
'type __iomem *var'.
Use the correct declaration to remove these warnings.
