Subject: usb: dwc3: gadget: purge dev_dbg() calls
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=ec5e795cdefb74b55c9fce918aa8a9226a8eec41;p=openwrt%2Fstaging%2Fblogic.git

usb: dwc3: gadget: purge dev_dbg() calls

The last few dev_dbg() messages are converted to
tracepoints and we can finally ignore dev_dbg()
messages during debug sessions.
