Subject: staging: rtl8188eu: remove get_right_chnl_for_iqk()
X-Git-Tag: v5.4-rc1~2324^2~251
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dee43f7ad325ecd58d60331e0fa1c1dfc0496201;p=platform%2Fkernel%2Flinux-rpi.git

staging: rtl8188eu: remove get_right_chnl_for_iqk()

The function get_right_chnl_for_iqk() only returns non zero values for
channels > 14. According to the TODO, code valid only for 5 GHz should
be removed.

- find and remove remaining code valid only for 5 GHz. Most of the obvious
  ones have been removed, but things like channel > 14 still exist.

Remove get_right_chnl_for_iqk() and the variable chn_index that is
used to save the return value. Replace the uses of chn_index with zero.

Remove the now unused define ODM_TARGET_CHNL_NUM_2G_5G.
