When DYNAMIC_DEBUG enabled, pr_debug() depends on KBUILD_MODNAME which also depends on the modules number in Makefile. 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. The related error with allmodconfig: CC [M] drivers/media/radio/si470x/radio-si470x-i2c.o CC [M] drivers/media/radio/si470x/radio-si470x-common.o In file included from include/linux/printk.h:257:0, from include/linux/kernel.h:13, from drivers/media/radio/si470x/radio-si470x.h:29, from drivers/media/radio/si470x/radio-si470x-common.c:115: ./arch/microblaze/include/asm/uaccess.h: In function 'access_ok': include/linux/dynamic_debug.h:66:14: error: 'KBUILD_MODNAME' undeclared (first use in this function) .modname = KBUILD_MODNAME, \ ^ include/linux/dynamic_debug.h:76:2: note: in expansion of macro 'DEFINE_DYNAMIC_DEBUG_METADATA' DEFINE_DYNAMIC_DEBUG_METADATA(descriptor, fmt); \ ^ include/linux/printk.h:263:2: note: in expansion of macro 'dynamic_pr_debug' dynamic_pr_debug(fmt, ##__VA_ARGS__) ^ ./arch/microblaze/include/asm/uaccess.h:101:3: note: in expansion of macro 'pr_debug' pr_debug("ACCESS fail: %s at 0x%08x (size 0x%x), seg 0x%08x\n", ^ Signed-off-by: Chen Gang <gang.chen.5i5j@gmail.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com> |
