Subject: wireless: Fix WARN_ON() with ieee802.11b
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=406f2388cc1f6e6c176305bd325cef230ce1afdd;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

wireless: Fix WARN_ON() with ieee802.11b

When the driver registers a IEEE80211_BAND_2GHZ band,
it can either be 802.11b or 802.11g. But when 802.11b rates
are registered "want" will be 3 (since 4 rates are being registered,
and each of those 4 rates will decrease "want").
Since this is a correct situation, there is no need to trigger
a WARN_ON() for this.
