The video driver doesn't properly remove all the notify handlers
on module unload.  This has a side effect of subdevices failing
to register on module reload, but sudden death looms if the
handlers trigger after the module is unloaded.

acpi_video_device_find_cap() used &p instead of *p
when calculating storage size, thus allocating
only 4 or 8 bytes instead of 12...

Also, kfree(NULL) is legal, so remove some unneeded checks.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
