| |
Hi all,
After merging the asm-generic tree, today's linux-next build (arm64 defconfig) failed like this:
drivers/char/mem.c: In function 'page_is_allowed': drivers/char/mem.c:66:16: error: implicit declaration of function 'devmem_is_allowed'; did you mean 'page_is_allowed'? [-Werror=implicit-function-declaration] 66 | return devmem_is_allowed(pfn); | ^~~~~~~~~~~~~~~~~ | page_is_allowed cc1: some warnings being treated as errors
Caused by commit
cdfde8f61a00 ("asm-generic: correct reference to GENERIC_LIB_DEVMEM_IS_ALLOWED")
arm64 does not have a separate declaration of devmem_is_allowed() and was using the asm-generic one by accident ... some other architectures may be in the same boat.
I have reverted that commit for today.
