[PATCH] usb: dwc3-exynos remove suspend clock unspecified debug message
From: Shuah Khan
Date: Tue Jan 10 2017 - 16:21:17 EST
dwc3-exynos prints debug message when suspend clock is not specified.
The suspend clock is optional and driver can work without it.
This debug message doesn't add any value and leads to confusion and
concern. Remove it.
