Subject: ath9k_hw: Remove CHANNEL_CW_INT
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fcb9a3de1e72cb271343aa9484a20c066b6c4eee;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ath9k_hw: Remove CHANNEL_CW_INT

This flag is used for indicating channel interference and
we currently do nothing with it, so remove it.
