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

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().
