+Subject: [PATCH] BSS coloring: fix CCA with multiple BSS
+
+Pass bss->ctx instead of drv->ctx in order to avoid multiple reports for
+the first bss. The first report would otherwise clear hapd->cca_color and
+subsequent reports would cause the iface bss color to be set to 0.
+In order to avoid any issues with cancellations, only overwrite the color
+based on hapd->cca_color if it was actually set.
+
+Fixes: 33c4dd26cd11 ("BSS coloring: Handle the collision and CCA events coming from the kernel")
