Hi Rob,
After merging the dt-rh tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
arch/powerpc/platforms/powernv/rng.c: In function 'rng_init_per_cpu':
arch/powerpc/platforms/powernv/rng.c:64:2: error: implicit declaration of function 'of_get_ibm_chip_id' [-Werror=implicit-function-declaration]
chip_id = of_get_ibm_chip_id(dn);
^
arch/powerpc/platforms/powernv/rng.c: In function 'rng_create':
arch/powerpc/platforms/powernv/rng.c:85:2: error: implicit declaration of function 'of_iomap' [-Werror=implicit-function-declaration]
rng->regs = of_iomap(dn, 0);
^
arch/powerpc/platforms/powernv/rng.c:85:12: error: assignment makes pointer from integer without a cast [-Werror]
rng->regs = of_iomap(dn, 0);
^
Caused by commit a4da0d50b2a0 ("powerpc: Implement
arch_get_random_long/int() for powernv") from the powerpc tree
interacting with commit b5b4bb3f6a11 ("of: only include prom.h on sparc")
from the dt-rh tree.
I added this merge fix patch (which will need to be sent to Linus when
these two trees get merged, or could be applied now to the powerpc tree):
