device_attributes: add sysfs_attr_init() for dynamic attributes
Made necessary by 6992f5334995af474c2b58d010d08bc597f0f2fe ("sysfs: Use one lockdep class per sysfs attribute"). Prevents further "key xxx not in .data" bug-reports. Although some attributes could probably be converted to static ones, this is left for people having hardware to test. Found by this semantic patch: @ init @ type T; identifier A; @@ T { ... struct device_attribute A; ... }; @ main extends init @ expression E; statement S; identifier err; T *name; @@ ... when != sysfs_attr_init(&name->A.attr); ( + sysfs_attr_init(&name->A.attr); if (device_create_file(E, &name->A)) S | + sysfs_attr_init(&name->A.attr); err = device_create_file(E, &name->A); ) While reviewing, I put the initialization to apropriate places.
