devres should be deallocated with devres_free() not kfree(). This bug
corrupts slab on IRQ request failure. Fix it.

[PATCH] sort the devres mess out2007-02-11T19:18:07ZAl Viroviro@ftp.linux.org.uk2007-02-11T15:41:31Zurn:sha1:5ea8176994003483a18c8fed580901e2125f8a83
* Split the implementation-agnostic stuff in separate files.
* Make sure that targets using non-default request_irq() pull
kernel/irq/devres.o
* Introduce new symbols (HAS_IOPORT and HAS_IOMEM) defaulting to positive;
allow architectures to turn them off (we needed these symbols anyway for
dependencies of quite a few drivers).
* protect the ioport-related parts of lib/devres.o with CONFIG_HAS_IOPORT.
