[PATCH v2] staging: rtl8192e: Fix conflicting types error with net_device.

[PATCH v2] staging: rtl8192e: Fix conflicting types error with net_device.

[Teddy Engel]

Add a pre-declaration of struct net_device so the compiler is able to
use rtl_pci.h / rtl_cam.h.

Fix for commit: 7dff0b27d9c842f88149bf611cbc0b59be1dcd3c:
[34/59] staging: rtl89192e: Remove unnecessary pre-declaration of struct
net_device.

You do that with a "Fixes:" tag, not the paragraph you wrote above :)

The documentation should explain how to do it, right?
