X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=c35fbd03ae22ca7d36622f63d0e58dadc77dfc44;p=deliverable%2Flinux.git

[media] au0828: Improve debug messages for urb_completion

Sometimes, it helps to know how much data was received by
urb_completion. Add that information to the optional debug
log.
