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

mei: bus: prefix device names on bus with the bus name

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

Add parent device name to the name of devices on bus to avoid device names collisions for same client UUID available from different MEI heads. Namely this prevents sysfs collision under /sys/bus/mei/device/

In the device part leave just UUID other parameters that are required for device matching are not required here and are just bloating the name.
