init dynamic bin_attribute structures 

Commit 6992f53349 ("sysfs: Use one lockdep
class per sysfs attribute.") 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);
    )
