Hi all, After merging the thermal tree, today's linux-next build (powerpc allyesconfig) failed like this: ld: drivers/thermal/imx_sc_thermal.o: in function `.imx_sc_thermal_get_temp': imx_sc_thermal.c:(.text.imx_sc_thermal_get_temp+0x68): undefined reference to `.imx_scu_call_rpc' ld: drivers/thermal/imx_sc_thermal.o: in function `.imx_sc_thermal_probe': imx_sc_thermal.c:(.text.imx_sc_thermal_probe+0x30): undefined reference to `.imx_scu_get_handle' Caused by commit ed0843633fee ("thermal: imx_sc: add i.MX system controller thermal support") I have added the following patch for today.
