From e70a57fa59bb7fefe063780a49e063d0d0f61863 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 11 Oct 2018 10:57:57 +0200 Subject: [PATCH] cxgb4: fix thermal configuration dependencies With CONFIG_THERMAL=m, we get a build error: drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.c: In function 'cxgb4_thermal_get_trip_type': drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.c:48:11: error: 'struct adapter' has no member named 'ch_thermal' Once that is fixed by using IS_ENABLED() checks, we get a link error against the thermal subsystem when cxgb4 is built-in: drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.o: In function `cxgb4_thermal_init': cxgb4_thermal.c:(.text+0x180): undefined reference to `thermal_zone_device_register' drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.o: In function `cxgb4_thermal_remove': cxgb4_thermal.c:(.text+0x1e0): undefined reference to `thermal_zone_device_unregister' Finally, since CONFIG_THERMAL can be =m, the Makefile fails to pick up the extra file into built-in.a, and we get another link failure against the cxgb4_thermal_init/cxgb4_thermal_remove files, so the Makefile has to be adapted as well to work for both CONFIG_THERMAL=y and =m.
