The DECLARE_BITMAP macro is not available in userspace headers. Fixes userspace compile error: error: expected specifier-qualifier-list before ‘DECLARE_BITMAP’
It's nonsense. This results in an incompatible structure, thus ABI would be broken completely (actually this will break the compile of ld10k1).
None of the exported headers after 'make headers_install' have definition of DECLARE_BITMAP macro. It is defined in include/linux/types.h which is different from include/uapi/linux/types.h and missing this definition and a few other things.
One option would be add DECLARE_BITMAP macro to include/uapi/linux/types.h and add include/linux/bitops.h to uapi.
Thoughts?
Are there any other headers like that? If this is the only one, leave it as is. The only program that reads this are some alsa-tools ones and they have already own DECLARE_BITMAP() definition. Adding the extra definition here will even break the compilation out of sudden.
