Hi Greg,

These patches do not work because this driver is divided into two
modules.

The driver is loaded in 2 different modules:
sudo insmod drivers/staging/rtl8192e/rtllib.ko
sudo insmod drivers/staging/rtl8192e/rtl8192e/r8192e_pci.ko

So this line is required:
priv->rtllib->SetWirelessMode = rtl92e_set_wireless_mode;
as one name is used in one module and one in the other module.

So when I suggested these fixes
1.  Patchset to combine both the modules into one module.
2.  Or resending v1 of the patchset.

to Dan Carpenter <dan.carpenter@...aro.org> and
Philipp Hortmann <philipp.g.hortmann@...il.com>, in their opinion both the
suggested fixes are incorrect, which I agree with.

I have yet to find a correct way to solve this problem. Please let me
know if you have any suggestions.

Yogesh
