If we are adding a multi-line function call can we please consider
following, on the top of this that matches earlier multi-line function
call in the same nvme_update_disk_into() :-
diff --git a/drivers/nvme/host/core.c b/drivers/nvme/host/core.c
index 3a0557ccc9fc..5cf0f801a95e 100644
--- a/drivers/nvme/host/core.c
+++ b/drivers/nvme/host/core.c
@@ -2115,7 +2115,7 @@ static void nvme_update_disk_info(struct gendisk
*disk,
nvme_config_write_zeroes(disk, ns);
set_disk_ro(disk, (id->nsattr & NVME_NS_ATTR_RO) ||
- test_bit(NVME_NS_FORCE_RO, &ns->flags));
+ test_bit(NVME_NS_FORCE_RO, &ns->flags));
}
static inline bool nvme_first_scan(struct gendisk *disk)
Otherwise, looks good.
