Subject: iwlwifi: mvm: remove rate_scale_data debugfs entry
X-Git-Tag: v3.12-rc1~132^2~84^2^2~55^2~12
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ab3077009f3e5237aaddaf0d5d139b1fd59d3b32;p=platform%2Fkernel%2Flinux-exynos.git

iwlwifi: mvm: remove rate_scale_data debugfs entry

This isn't very informative and can be deduced from rate_scale_table.
Remove as a preparation for dropping iwl_rs_rate_info.ieee.
