From: Brian Norris Date: Sat, 29 Oct 2022 01:45:34 +0000 (-0700) Subject: usb: ehci-pci: Set PROBE_PREFER_ASYNCHRONOUS X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ee9834636f9b07fe1dcf3fffbb325318cdb267d5;p=linux.git usb: ehci-pci: Set PROBE_PREFER_ASYNCHRONOUS This driver often takes on the order of 8ms to start, but every little bit counts. 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.
