From: Brian Norris Date: Sat, 29 Oct 2022 01:45:35 +0000 (-0700) Subject: usb: xhci-pci: Set PROBE_PREFER_ASYNCHRONOUS X-Git-Tag: v6.6.7~3884^2~113 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4c2604a9a6899bab195edbee35fc8d64ce1444aa;p=platform%2Fkernel%2Flinux-starfive.git usb: xhci-pci: Set PROBE_PREFER_ASYNCHRONOUS This driver often takes on the order of 10ms to start, but in some cases takes more than 100ms. It shouldn't have many cross-device dependencies to race with, nor racy access to shared state with other drivers, so this should be a relatively low risk change. This driver was pinpointed as part of a survey of top slowest initcalls (i.e., are built in, and probing synchronously) on a lab of ChromeOS systems.
