Many build errors happen when CONFIG_PROC_FS is not enabled.
This is not new -- I also saw it about 2 weeks ago but did not analyze or report it.


use of PDE_DATA() (from <linux/proc_fs.h>):

drivers/net/wireless/hostap/hostap_ap.c:85:2: error: implicit declaration of function 'PDE_DATA' [-Werror=implicit-function-declaration]

Al, would it make sense to have a stub for PDE_DATA() in
<linux/proc_fs.h> when CONFIG_PROC_FS is not enabled?
