| |
The patch
spi: pic32-sqi: fixup wait_for_completion_timeout return handling
has been applied to the spi tree at
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git
All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
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 33d5097dbf650b84238c6ebdfea4a335f64f9608 Mon Sep 17 00:00:00 2001 From: Nicholas Mc Guire <hofrat@osadl.org> Date: Sat, 23 Jul 2016 21:08:35 +0200 Subject: [PATCH] spi: pic32-sqi: fixup wait_for_completion_timeout return handling
wait_for_completion_timeout returns unsigned long not int so the check for <= 0 should be == 0 here, and the type unsigned long. The function return is set to -ETIMEDOUT to reflect the actual problem.
