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 5223db0b10c7917d7c6b4f7d8e2c0af0eb1158f5 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Fri, 13 Jan 2017 13:33:02 +0100 Subject: [PATCH] spi: fsl: Use kcalloc() in of_fsl_spi_get_chipselects() A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus reuse the corresponding function "kcalloc". This issue was detected by using the Coccinelle software.
