This one looks wrong. pdata is copied by the internals of
omap_device_build(), which includes the 'regs' pointer, so it should not
be freed after a successful call to omap_device_build(). (It should,
however, be freed after an unsuccessful call.)
BTW, you want to copy Paul Walmsley with this patch (address in Cc).
