Some ATA drivers use the SCSI host template, a series of interwoven macros, to aid with initialisation. Some of these macros conflict, resulting in the over-writing of previously set values.
This is known behaviour and can be safely ignored. Fixes the following W=1 kernel build warning(s): In file included from drivers/ata/ahci_dm816.c:16: drivers/ata/ahci.h:387:16: warning: initialized field overwritten [-Woverride-init] drivers/ata/ahci_dm816.c:138:2: note: in expansion of macro ‘AHCI_SHT’ drivers/ata/ahci.h:387:16: note: (near initialization for ‘ahci_dm816_platform_sht.can_queue’) drivers/ata/ahci_dm816.c:138:2: note: in expansion of macro ‘AHCI_SHT’ drivers/ata/ahci.h:391:17: warning: initialized field overwritten [-Woverride-init] drivers/ata/ahci_dm816.c:138:2: note: in expansion of macro ‘AHCI_SHT’ drivers/ata/ahci.h:391:17: note: (near initialization for ‘ahci_dm816_platform_sht.sdev_attrs’) drivers/ata/ahci_dm816.c:138:2: note: in expansion of macro ‘AHCI_SHT’ Cc: Jens Axboe <ax...@kernel.dk> Cc: linux-...@vger.kernel.org Signed-off-by: Lee Jones <lee.jo...@linaro.org> --- drivers/ata/Makefile | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/ata/Makefile b/drivers/ata/Makefile index b8aebfb14e825..d24bf4d2b08d6 100644 --- a/drivers/ata/Makefile +++ b/drivers/ata/Makefile @@ -1,5 +1,7 @@ # SPDX-License-Identifier: GPL-2.0 +CFLAGS_ahci_dm816.o = $(call cc-disable-warning, override-init) + obj-$(CONFIG_ATA) += libata.o # non-SFF interface -- 2.25.1
