Actually this is not equivalent to what was there before.

With Jisheng's patch, with CONFIG_PM disabled, he adds 16 bytes to 
the
structure. You might thing today, 16 bytes is nothing. True, but 
on a
64MB RAM devices, it's something.

That might not be a reason to reject the patch, but it's not only 
a
"modernisation patch".

Cheers.
