From dc4e9e2aa82a697ff1fccf6dbdd9f648afc7d71a Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Fri, 28 Oct 2022 15:56:37 -0700 Subject: [PATCH] mmc: sdhci-pci: Set PROBE_PREFER_ASYNCHRONOUS This driver often takes on the order of 10ms to start, but in some cases as much as 190ms. 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. We've done similarly with a variety of other MMC host drivers already. 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.
