Subject: cfg80211: fix DFS channel recovery timeout
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c532a58b0fb4b2b3309e6b87bafb44f36808aa6f;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

cfg80211: fix DFS channel recovery timeout

The timeout was not properly converted from msecs
to jiffies. As a result channel transition to
NL80211_DFS_USABLE was delayed depending on
CONFIG_HZ configuration, e.g. HZ=100 would delay
the NOP from 30 minutes to 300 minutes.
