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 b7cd1b1386ff46e60452ad1f16530645761ca7b8 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Mon, 6 Mar 2017 17:34:48 +0100 Subject: [PATCH] regulator: core: use snprintf() instead of scnprintf() When creating the link to the device sysfs entry, the regulator core calls scnprintf() and then checks if the returned value is greater or equal than the buffer size. The former can never happen as scnprintf() returns the number of bytes that were actually written to the buffer, not the bytes that *would* have been written. Use the right function in this case: snprintf().
