The current debug parameter is applied to rtlwifi, which means that all loaded drivers have the same level of debugging applied. In addition, the previous method requires a two-step load process to enable debugging. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
