From: Arnd Bergmann <arnd@xxxxxxxx>
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.
Fixes: 3c816d950a49 ("ARM: pxa: move clk register definitions to driver")
