AMD Has A One-Liner To Help Speed Up Linux System Resume Time 10

Michael Larabel, reporting at Phoronix: AMD engineers have been working out many quirks and oddities in system suspend/resume handling to make it more reliable on their hardware particularly around Ryzen laptops. In addition to suspend/resume reliability improvements and suspend-to-idle (s2idle) enhancements, one of their engineers also discovered an easy one-liner as a small step to speeding up system resume time. AMD engineer Basavaraj Natikar realized a missing check in the USB XHCI driver can avoid an extra 120ms delay during system resume time. It's only 120 ms, but it's a broad win given it's for the XHCI driver code and part of their larger effort of improving the AMD Ryzen platform on Linux and this 120ms savings is from altering one line of code.
