patch "usb: gadget: udc: renesas_usb3: should fail if devm_phy_get() returns" added to usb-testing

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

usb: gadget: udc: renesas_usb3: should fail if devm_phy_get() returns

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-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 usb-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.

Subject: usb: gadget: udc: renesas_usb3: should fail if devm_phy_get() returns
error

This patch fixes an issue that this driver ignores errors other than the non-existence of the device, f.e. a memory allocation failure in devm_phy_get(). So, this patch replaces devm_phy_get() with devm_phy_optional_get().
