Subject: iwmc3200wifi: simplify calibration map
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=fd2c7fe0b4dedc34ea0a2a72e00648bd2b8c7c3a;p=openwrt%2Fstaging%2Fblogic.git

iwmc3200wifi: simplify calibration map

The patch simplifies calibration map by combining the init_calib_map
and periodic_calib_map into one calib_map in struct iwm_conf. Now the
initial calibration map is stored in the lower 16 bits of calib_map
and the periodic calibration map is stored in the higher 16 bits.
