Hi all, After merging the char-misc tree, today's linux-next build (x86 allmodconfig) failed like this: /tmp/next/build/drivers/mmc/host/rtsx_pci_sdmmc.c: In function 'sd_request': /tmp/next/build/drivers/mmc/host/rtsx_pci_sdmmc.c:809:17: error: unused variable 'dev' [-Werror=unused-variable] 809 | struct device *dev = &host->pdev->dev; | ^~~ /tmp/next/build/drivers/mmc/host/rtsx_pci_sdmmc.c: In function 'sdmmc_set_ios': /tmp/next/build/drivers/mmc/host/rtsx_pci_sdmmc.c:1084:17: error: unused variable 'dev' [-Werror=unused-variable] 1084 | struct device *dev = &host->pdev->dev; | ^~~ /tmp/next/build/drivers/mmc/host/rtsx_pci_sdmmc.c: In function 'sdmmc_get_ro': /tmp/next/build/drivers/mmc/host/rtsx_pci_sdmmc.c:1133:17: error: unused variable 'dev' [-Werror=unused-variable] 1133 | struct device *dev = &host->pdev->dev; | ^~~ /tmp/next/build/drivers/mmc/host/rtsx_pci_sdmmc.c: In function 'sdmmc_get_cd': /tmp/next/build/drivers/mmc/host/rtsx_pci_sdmmc.c:1159:17: error: unused variable 'dev' [-Werror=unused-variable] 1159 | struct device *dev = &host->pdev->dev; | ^~~ /tmp/next/build/drivers/mmc/host/rtsx_pci_sdmmc.c: In function 'sdmmc_switch_voltage': /tmp/next/build/drivers/mmc/host/rtsx_pci_sdmmc.c:1258:17: error: unused variable 'dev' [-Werror=unused-variable] 1258 | struct device *dev = &host->pdev->dev; | ^~~ /tmp/next/build/drivers/mmc/host/rtsx_pci_sdmmc.c: In function 'sdmmc_execute_tuning': /tmp/next/build/drivers/mmc/host/rtsx_pci_sdmmc.c:1311:17: error: unused variable 'dev' [-Werror=unused-variable] 1311 | struct device *dev = &host->pdev->dev; | ^~~ cc1: all warnings being treated as errors Caused by commit 7570fb41e450ba37 ("mmc: rtsx: Let MMC core handle runtime PM") I have used the char-misc tree from yesterday instead.
