Subject: [PATCH] staging: r8188eu: remove channel parameters from rtw_sitesurvey_cmd
The rtw_sitesurvey_cmd function may receive an array of channels in the
ch and ch_num parameters. All of the callers set ch = NULL and ch_num = 0.
Remove the two parameters from rtw_sitesurvey_cmd and the code to process
them.
