Subject: b43: HT-PHY: correct 0x2059 radio init
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a5f377fb9c9758b248773c5b8b1a20d4e7e2c982;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

b43: HT-PHY: correct 0x2059 radio init

Sometimes additional steps are performed while initializing 2059 radio.
We did not find the condition yet, so make it always true for now.
