Subject: ath9k: remove temp variable ratecode from ath_rx_prepare()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=14077f5b7a28bdcd166faed2c0b36fad9f3eadda;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ath9k: remove temp variable ratecode from ath_rx_prepare()

Its just a distraction when reading the code, instead use the
rx_stats->rs_rate directly.
