From 93f1d3e4b59cf2e7ef31eaf1131480897b040e97 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 8 Jul 2019 14:42:51 +0200 Subject: remoteproc: stm32: fix building without ARM SMCC When compile testing this driver without SMCC support enabled, we get a link error: drivers/remoteproc/stm32_rproc.o: In function `stm32_rproc_start': stm32_rproc.c:(.text+0x776): undefined reference to `__arm_smccc_smc' drivers/remoteproc/stm32_rproc.o: In function `stm32_rproc_stop': stm32_rproc.c:(.text+0x92c): undefined reference to `__arm_smccc_smc' Make the actual call to arm_smccc_smc conditional on the Kconfig symbol controlling its implementation.
