From 514b2262ade48a0503ac6aa03c3bfb8c5be69b21 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sat, 16 Nov 2024 00:05:18 +0100 Subject: firmware: arm_scmi: Fix i.MX build dependency The newly added SCMI vendor driver references functions in the protocol driver but needs a Kconfig dependency to ensure it can link, essentially the Kconfig dependency needs to be reversed to match the link time dependency: | arm-linux-gnueabi-ld: sound/soc/fsl/fsl_mqs.o: in function `fsl_mqs_sm_write': | fsl_mqs.c:(.text+0x1aa): undefined reference to `scmi_imx_misc_ctrl_set' | arm-linux-gnueabi-ld: sound/soc/fsl/fsl_mqs.o: in function `fsl_mqs_sm_read': | fsl_mqs.c:(.text+0x1ee): undefined reference to `scmi_imx_misc_ctrl_get' This however only works after changing the dependency in the SND_SOC_FSL_MQS driver as well, which uses 'select IMX_SCMI_MISC_DRV' to turn on a driver it depends on. This is generally a bad idea, so the best solution is to change that into a dependency. To allow the ASoC driver to keep building with the SCMI support, this needs to be an optional dependency that enforces the link-time dependency if IMX_SCMI_MISC_DRV is a loadable module but not depend on it if that is disabled.
