The structures rate_control_ops are only passed as an argument to the
functions ieee80211_rate_control_{register/unregister}. This argument is
of type const, so rate_control_ops having this property can also be
declared as const.
Done using Coccinelle:

The content of your patch is OK; however, your subject is not. By convention,
"net: wireless: realtek:" is assumed. We do, however, include "rtlwifi:" to
indicate which part of drivers/net/wireless/realtek/ is referenced.
NACK

Ok, I will send a v2 with the correct subject. Thanks for the input.

In addition, the first part of the description is useful and the file
size information is reasonable too, but ~20 lines of coccinelle scripts
in the commit message is rather pointless.
