Subject: ath9k: Remove ATH9K_BEACON_PERIOD mask
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f29f5c0882bdd58c42b8176ee0b578f92589fda2;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ath9k: Remove ATH9K_BEACON_PERIOD mask

Earlier beacon_interval is used to hold interval value and
some flags (ATH9K_BEACON_ENA &ATH9K_BEACON_PERIOD). So to
extract interval ATH9K_BEACON_PERIOD is used. Those flags
were completely removed. So masking beacon_interval is
not required.
