[PATCH 4/8] ALSA: usb-audio: scarlett2: Remove interrupt debug message

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Just ignore instead of printing an error if the interrupt data is not
the expected length. This check was for development and the condition
has not been observed.
