Thank you! [1/1] soc: ti: knav: Drop unnecessary check for property presence commit: 8737e167dc55cc00c5818b408f47ba03b6ddb25b All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent up the chain during the next merge window (or sooner if it is a relevant 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. [1] https://git.kernel.org/pub/scm/linux/kernel/git/ti/linux.git

of_property_read_u32() returns -EINVAL if a property is not present, so the preceeding check for presence with of_get_property() can be dropped. This is part of a larger effort to remove callers of of_get_property() and similar functions. of_get_property() leaks the DT struct property and data pointers which is a problem for dynamically allocated nodes which may be freed.
