   Not necessarily, it's your call. But all the patches are fixes.

   No, the patches ware all the result of the code reviews...

   No, they're definitely not cleanups and all have the "Fixes:" tags, so going
to end up in the stable trees (some already have).
   There's going to be 10-patch series soon, all fixing the deferred probing due
to platfrorm_get_irq()...
   Luckily, the USB tree doesn't shave the 3rd kind of platfrorm_get_irq() bugs:
treating 0 as error and returning it immediately along with the negative values,
without doing the remaining part of probe...
