Remove the incorrect #ifdef and instead of a Kconfig dependency to only allow building the driver when CONFIG_GENERIC_MSI_IRQ is enabled. This symbol is always present when PCI_MSI or ARM_GIC_V3_ITS are enabled, both of which should be present on kernels that can run on Qualcomm SoCs. The 'select RESET_CONTROLLER' in combination with this dependency unfortunately causes a dependency loop and this is a user-visible symbol, so it's better to change both to 'depends on'. Fixes: 519b6274a777 ("scsi: ufs: qcom: Add MCQ ESI config vendor specific ops") Fixes: 13e7accb81d6 ("genirq: Get rid of GENERIC_MSI_IRQ_DOMAIN") Signed-off-by: Arnd Bergmann Reviewed-by: Manivannan Sadhasivam --- Not sure if this is the best solution, both the GENERIC_MSI_IRQ dependencies and the RESET_CONTROLLER dependencies are a bit inconsistent already. Feel free to pick another approach that addresses both of the bugs I found. --- drivers/ufs/host/Kconfig | 3 ++- drivers/ufs/host/ufs-qcom.c | 8 -------- 2 files changed, 2 insertions(+), 9 deletions(-) diff --git a/drivers/ufs/host/Kconfig b/drivers/ufs/host/Kconfig index 139064e70a34..663881437921 100644 --- a/drivers/ufs/host/Kconfig +++ b/drivers/ufs/host/Kconfig @@ -57,8 +57,9 @@ config SCSI_UFS_DWC_TC_PLATFORM config SCSI_UFS_QCOM tristate "QCOM specific hooks to UFS controller platform driver" depends on SCSI_UFSHCD_PLATFORM && ARCH_QCOM + depends on GENERIC_MSI_IRQ + depends on RESET_CONTROLLER select QCOM_SCM if SCSI_UFS_CRYPTO - select RESET_CONTROLLER help This selects the QCOM specific additions to UFSHCD platform driver.
