Change all instances using __ATTR*() to now use DEVICE_ATTR*(). Example of old: struct device_attribute dev_attr_##_name = __ATTR(_name, _mode, _show, _store) Example of new: static DEVICE_ATTR(foo, S_IWUSR | S_IRUGO, show_foo, store_foo) Signed-off-by: Kelsey Skunberg --- drivers/pci/pci-sysfs.c | 59 +++++++++++++++++++---------------------- 1 file changed, 27 insertions(+), 32 deletions(-) diff --git a/drivers/pci/pci-sysfs.c b/drivers/pci/pci-sysfs.c index 965c72104150..8af7944fdccb 100644 --- a/drivers/pci/pci-sysfs.c +++ b/drivers/pci/pci-sysfs.c @@ -464,9 +464,7 @@ static ssize_t dev_rescan_store(struct device *dev, } return count;
