implicit declaration of function ‘autosuspend_enter’ when compiling on BeagleBoneBlack #23

Hi,

When I try to compile this on a BBB, I get the following error:

root@beaglebone:~/rtl8723bu# make
make ARCH=arm CROSS_COMPILE= -C /lib/modules/3.8.13-bone79/build M=/root/rtl8723bu  modules

make: *** [modules] Error 2

It looks like the function autosuspend_enter is defined in os_dep/usb_intf.c, but I can't find it's declaration. I pulled the most recent code today.

Thanks for any help you can give.

Your kernel configuration obviously defines CONFIG_USB_SUSPEND, which does not happen for x86. I suspect it is an ARM thing. I added the necessary header include to fix the build error.

Note: Having CONFIG_USB_SUSPEND defined compiles quite a bit of code that I have never tested.

Thanks for adding that header. Things now compile and install fine, but I'm unable to connect to a wpa network. I'm not sure what to test next; can you give me some guidance on this?

I'm trying to use wpa_supplicant like so: root@beaglebone:~# wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf ioctl[SIOCSIWAP]: Operation not permitted ioctl[SIOCSIWENCODEEXT]: Invalid argument ioctl[SIOCSIWENCODEEXT]: Invalid argument root@beaglebone:~# dhclient wlan0

When I look at dmesg, I see the following:
