patch "usb: chipdea: core: fix return -EINVAL if request role is the same" added to usb-linus

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

usb: chipdea: core: fix return -EINVAL if request role is the same

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

with current role

It should not return -EINVAL if the request role is the same with current role, return non-error and without do anything instead.
