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.
