This is a note to let you know that I've just added the patch titled
test_firmware: fix missing unlock on error in
to my driver-core git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git in the driver-core-testing 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 be merged to the driver-core-next branch sometime soon, after it passes testing, and the merge window is open.
If you have any questions about this process, please let me know.
