This is a note to let you know that I've just added the patch titled
staging: kpc2000: fix error return code in kp2000_pcie_probe()
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.

Subject: staging: kpc2000: fix error return code in kp2000_pcie_probe()
Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function. Also
removed var 'rv' since we can use 'err' instead.
Fixes: 7dc7967fc39a ("staging: kpc2000: add initial set of Daktronics drivers")
