You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark From 123af9043e93cb6f235207d260d50f832cdb5439 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 15 Jan 2018 11:08:38 +0300 Subject: [PATCH] ASoC: au1x: Fix timeout tests in au1xac97c_ac97_read() The loop timeout doesn't work because it's a post op and ends with "tmo" set to -1. I changed it from a post-op to a pre-op and I changed the initial the starting value from 5 to 6 so we still iterate 5 times. I left the other as it was because it's a large number.
