Subject: usb: dwc2: gadget: Set the default EP max packet value as 8 bytes
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=9b2667f1f30e91becc3751acd5cffaedcf68e098;p=deliverable%2Flinux.git

usb: dwc2: gadget: Set the default EP max packet value as 8 bytes

Set the default EP max packet value as 8 bytes, because in the case
of low-speed, 'ep_mps' is not set. Thus, the default value of 'ep_mps'
should be considered for the case of low-speed.
