This is a note to let you know that I've just added the patch titled

staging: vchiq: call unregister_chrdev_region() when driver

to my staging git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git in the staging-linus branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

If you have any questions about this process, please let me know.

This undoes the previous call to alloc_chrdev_region() on failure, and is probably what was meant originally given the label name.
