This reverts commit
2ad69ac5976191e9bb7dc4044204a504653ad1bb. It
causes wireless device disappear when we get -EPROTO error form USB
request. I encounter such situation occasionally when resume form
suspend with RT3070 adapter:
[ 289.619985] ieee80211 phy0: rt2x00usb_vendor_request: Error - Vendor Request 0x06 failed for offset 0x0404 with error -71

Without the patch, except printing error, device works just fine after
resume.
Currently after timeouts and REGISTER_BUSY_COUNT tuning, we should
not have any "endless loop", though we can wait quite long when driver
is trying to communicate with the device through non functioning USB
connection. Generally the problem that commit

Add SSID information to the net-detect indication to userspace. Fetch

Since the net-detect information is stored in cfg80211, and in theory
it could change while we are waking up and reading the matched

brcmfmac: correct .disconnect() callback while connecting
When the driver has sent a join iovar to the firmware it waits
for the events to report result of the connection. However, the
wpa_supplicant will request a .disconnect() after a timeout. So
upon calling .disconnect() the interface state may still be
CONNECTING. Clear the CONNECTING bit as well.

net: wireless: rtlwifi: rtl8192ee: Fix compilation of the driver
In the Makefile for this driver, the wrong Kconfig option is used

net: wireless: rtlwifi: Do not always include drivers in obj-m
In four of the rtlwifi drivers, the Makefile contains superfluous
statements indicating the compilation of the driver as an LKM
regardless of the corresponding Kconfig option.
If the corresponding option is set to 'y', the build system will then
see the object file in obj-m and obj-y, which leads to a compilation
as a built-in only. Even though this leads to the desired behavior,
the unconditional appearance in obj-m is confusing for someone reading
the Makefile.
This patch removes the superfluous Makefile statements.
