For wmfw format v2 and later the coefficient name strings have a length field and are NOT null-terminated. Use kasprintf() to convert the unterminated string into a null-terminated string in an allocated buffer.
The previous code handled this duplication incorrectly using kmemdup() and getting the length from a strlen() of the (unterminated) source string. This resulted in creating a string that continued up to the next byte in the firmware file that just happened to be 0x00.

[1/1] firmware: cs_dsp: Fix overrun of unterminated control name string commit: 5b933c7262c5b0ea11ea3c3b3ea81add04895954
All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a 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.
Thanks, Mark
