If anyone has any objections, please let me know. ------------------ From: Takashi Iwai [ Upstream commit b198499c7d2508a76243b98e7cca992f6fd2b7f7 ] Apparently the Raptor Lake-P reference firmware configures the PIO log size correctly, but some vendor BIOSes, including at least ASUSTeK COMPUTER INC. Zenbook UX3402VA_UX3402VA, do not. Apply the quirk for Raptor Lake-P. This prevents kernel complaints like: DPC: RP PIO log size 0 is invalid and also enables the DPC driver to dump the RP PIO Log registers when DPC is triggered. Note that the bug report also mentions 8086:a76e, which has been already added by 627c6db20703 ("PCI/DPC: Quirk PIO log size for Intel Raptor Lake Root Ports").
