+Subject: [PATCH] brcmfmac: fix setting primary channel for 80 MHz width
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+First of all it changes the way we calculate primary channel offset. If
+we use e.g. 80 MHz channel with primary frequency 5180 MHz (which means
+center frequency is 5210 MHz) it makes sense to calculate primary offset
+as -30 MHz.
+Then it fixes values we compare primary_offset with. We were comparing
+offset in MHz against -2 or 2 which was resulting in picking a wrong
+primary channel.
