Hi all, After merging the arm-soc tree, today's linux-next build (powerpc allnoconfig) failed like this: drivers/of/address.c: In function 'of_iomap': drivers/of/address.c:907:10: error: implicit declaration of function 'ioremap_np'; did you mean 'ioremap_wt'? [-Werror=implicit-function-declaration] 907 | return ioremap_np(res.start, resource_size(&res)); | ^~~~~~~~~~ | ioremap_wt drivers/of/address.c:907:10: warning: returning 'int' from a function with return type 'void *' makes pointer from integer without a cast [-Wint-conversion] 907 | return ioremap_np(res.start, resource_size(&res)); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/of/address.c: In function 'of_io_request_and_map': drivers/of/address.c:942:7: warning: assignment to 'void *' from 'int' makes pointer from integer without a cast [-Wint-conversion] 942 | mem = ioremap_np(res.start, resource_size(&res)); | ^ lib/devres.c: In function '__devm_ioremap': lib/devres.c:47:10: error: implicit declaration of function 'ioremap_np'; did you mean 'ioremap_wt'?
