      init dynamic bin_attribute structures · f937331b
      由 Wolfram Sang 提交于 
      Commit 6992f533 ("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;

    (

      MIPS: TXx9: Fix error handling. · 70ebadc8
      由 Julia Lawall 提交于 
      Error handling code following a kzalloc should free the allocated data.
Error handling code following an ioremap should iounmap the allocated data.

The semantic match that finds the first problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
