Subject: [PATCH v2 1/3] PCI: sysfs: Define device attributes with DEVICE_ATTR*()
Date: Tue, 13 Aug 2019 14:45:11 -0600 [thread overview]
Message-ID: <20190813204513.4790-2-skunberg.kelsey@gmail.com> (raw)
In-Reply-To: <20190813204513.4790-1-skunberg.kelsey@gmail.com>
Defining device attributes should be done through the helper
DEVICE_ATTR*(_name, _mode, _show, _store). 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)
