Subject: usb: dwc3: gadget: WARN() in case of unknown IRQ
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=e9f2aa871c732acfe29c3ba5e6b541b2aa786778;p=deliverable%2Flinux.git

usb: dwc3: gadget: WARN() in case of unknown IRQ

if an unknown IRQ event is triggered, that means
the HW is really misbehaving. Instead of printing
a debug message, let's WARN() so users report
when that happens.
