Subject: [PATCH] init dynamic bin_attribute structures

Commit 6992f5334995af474c2b58d010d08bc597f0f2fe introduced this requirement.
First, at25 was fixed manually. Then, other occurences were found with
coccinelle and the following semantic patch. Results were reviewed and fixed
up:

@ init @
identifier struct_name, bin;
@@

	struct struct_name {
		...
		struct bin_attribute bin;
		...
	};

@ main extends init @
expression E;
statement S;
identifier name, err;
@@

(
	struct struct_name *name;
|
-	struct struct_name *name = NULL;
+	struct struct_name *name;
)
	...
(
	sysfs_bin_attr_init(&name->bin);
|
+	sysfs_bin_attr_init(&name->bin);
	if (sysfs_create_bin_file(E, &name->bin))
		S
|
+	sysfs_bin_attr_init(&name->bin);
	err = sysfs_create_bin_file(E, &name->bin);
)
