Subject: staging: rtl8192u: r8192U_core: fix negative noise value
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f517f3bf07f1f776f12b2413dbefa21523021ac1;p=openwrt%2Fstaging%2Fblogic.git

staging: rtl8192u: r8192U_core: fix negative noise value

ieee80211_rx_stats.noise is of type uint8, so it shouldn't be assigned a
negative number. Assigning it 0x100 - 98, which is the equivalent
to -98 dBm when IW_QUAL_DBM is set.
