The related information in "scripts/Makefile.lib" line 94: # $(modname_flags) #defines KBUILD_MODNAME as the name of the module it will # end up in (or would, if it gets compiled in) # Note: Files that end up in two or more modules are compiled without the # KBUILD_MODNAME definition. The reason is that any made-up name would # differ in different configs. For this case, 'radio-si470x-i2c.o' and 'radio-si470x-common.o' are in one line, so cause compiling issue. And 'uaccess.h' is a common shared header (not specially for drivers), so use pr_devel() instead of is OK.
