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 99c4f70df3a6446c56ca817c2d0f9c12d85d4e7c Mon Sep 17 00:00:00 2001 From: Stephan Gerhold <stephan@gerhold.net> Date: Wed, 6 Nov 2019 18:31:24 +0100 Subject: [PATCH] regulator: ab8500: Remove AB8505 USB regulator The USB regulator was removed for AB8500 in commit 41a06aa738ad ("regulator: ab8500: Remove USB regulator"). It was then added for AB8505 in commit 547f384f33db ("regulator: ab8500: add support for ab8505"). However, there was never an entry added for it in ab8505_regulator_match. This causes all regulators after it to be initialized with the wrong device tree data, eventually leading to an out-of-bounds array read. Given that it is not used anywhere in the kernel, it seems likely that similar arguments against supporting it exist for AB8505 (it is controlled by hardware). Therefore, simply remove it like for AB8500 instead of adding an entry in ab8505_regulator_match.
