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 989ffc7bd6b0f5ea3423631981f87fde495a8acb Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 22 Apr 2016 12:55:24 +0300 Subject: [PATCH] spi: pic32-sqi: silence array overflow warning We read one element beyond the end of the array when we access "rdesc[i + 1]" so it causes a static checker warning. It's harmless because we write over it again on the next line. But let's just silence the warning.
