sparse points out an embarrasing bug in an older patch of mine,
which uses the register offset instead of an __iomem pointer:

drivers/clk/pxa/clk-pxa3xx.c:167:9: sparse: sparse: Using plain integer as NULL pointer

Unlike sparse, gcc and clang ignore this bug and fail to warn
because a literal '0' is considered a valid representation of
a NULL pointer.
