Subject[PATCH] spi: omap2-mcspi: fix blatant abuse of the resource subsystem
Date
Aua. This really hurts. I wonder how this could ever be admitted to
the Linux kernel...
Further comments suppressed because the would most likely violate the
CDA.

If someone should not grasp what this patch does, they should consider
what happens upon unloading/reloading the kernel module.
