Subject: ath9k: remove unneeded calculation of minimal calibration power
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6eb90d46c59a75ceeccfef7c6c6705fb64b593dc;p=linux-beck.git

ath9k: remove unneeded calculation of minimal calibration power

Remove tMinCalPower from ath9k_hw_set_def_power_cal_table(), as it's
never used.  Remove corresponding arguments of the functions calculating
that value.

Original patch by Prarit Bhargava <prarit@redhat.com>
