Subject: rt2x00: Code clean up in rt2800lib.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8c6728b08ee589ae3c7a75f0d1aa5d73a9c042f1;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

rt2x00: Code clean up in rt2800lib.

Make the code in rt2800_get_default_vgc more understandable and
readable, especially for the 5GHz band values.
