Can't bring up wl1271_sdio (wlcore_sdio) driver second time

Please, advice me what can I do with a same problem like in a post http://e2e.ti.com/support/low_power_rf/f/307/t/181835.aspx.

I have a next environment:

1. BeagleBoard-xM C2.
2. Linux 2.6.37.
3. TiWi-BLE module (COM6L-BLE) from LS Reseach.
4. Drivers from compat backports-3.11-rc3-1.
5. I have configured pins correctly, because I successfully brought up wlan0 interface first time.

So, symptoms are the next:

First "modprobe":

modprobe wlcore_sdio

[   28.873321] bus: 'sdio': add driver wl1271_sdio
[   28.878265] bus: 'sdio': driver_probe_device: matched device mmc1:0001:1 with driver wl1271_sdio

[   29.110839] bus: 'platform': add device wl12xx
[   29.115844] PM: Adding info for platform:wl12xx

But after that

rmmod wlcore_sdio

modprobe wlcore_sdio

I have errors:

[  493.726196] bus: 'sdio': add driver wl1271_sdio
[  493.731140] bus: 'sdio': driver_probe_device: matched device mmc1:0001:1 with driver wl1271_sdio

[  493.801116] wl1271_sdio: probe of mmc1:0001:2 failed with error -110

It even not enter to wl1271_probe.

Interrupts before rmmod wlcore_sdio:

So,  I have no wl12xx interrupt:

297: 0 GPIO wl12xx

Me and Divya share the same setup, after applying the PM runtime patch from the following link
