Some drivers use debugfs_real_fops() even when CONFIG_DEBUG_FS is disabled,
which now leads to a build error:
In file included from include/linux/list.h:9:0,
from include/linux/wait.h:7,
from include/linux/wait_bit.h:8,
from include/linux/fs.h:6,
from drivers/net/wireless/broadcom/b43legacy/debugfs.c:26:
drivers/net/wireless/broadcom/b43legacy/debugfs.c: In function 'b43legacy_debugfs_read':
drivers/net/wireless/broadcom/b43legacy/debugfs.c:224:23: error: implicit declaration of function 'debugfs_real_fops'; did you mean 'debugfs_create_bool'? [-Werror=implicit-function-declaration]
My first impulse was to add another 'static inline' dummy function
returning NULL for it, which would work fine. However, most callers
feed the pointer into container_of(), so it seems a little dangerous
here. Since all the callers are inside of a read/write file operation
that gets eliminated in this configuration, so having an 'extern'
declaration seems better here. If it ever gets used in a dangerous
way, that will now result in a link error.
