Partially Revert "of: fix sparse warnings in fdt, irq, reserved mem, and resolver code"
A change to function pointers that was meant to address a sparse warning turned out to cause hundreds of new gcc-7 warnings: include/linux/of_irq.h:11:13: error: type qualifiers ignored on function return type [-Werror=ignored-qualifiers] drivers/of/of_reserved_mem.c: In function '__reserved_mem_init_node': drivers/of/of_reserved_mem.c:200:7: error: type qualifiers ignored on function return type [-Werror=ignored-qualifiers] int const (*initfn)(struct reserved_mem *rmem) = i->data; Turns out the sparse warnings were spurious and have been fixed in upstream sparse since 0.5.0 in commit "sparse: treat function pointers as pointers to const data". This partially reverts commit 17a70355ea576843a7ac851f1db26872a50b2850. Fixes: 17a70355ea57 ("of: fix sparse warnings in fdt, irq, reserved mem, and resolver code") Reported-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Rob Herring <robh@kernel.org>
