The patch
ASoC: Intel: Skylake: fix typo in sizeof
has been applied to the asoc tree at
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
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

The size of the pointer to a data structure to send is erroneously passed to sst_ipc_tx_message_wait() as its tx_bytes argument. It should be given the size of the pointed skl_ipc_dxstate_info structure instead.
Coincidentally, both the pointer and the structure have the same size of 8 bytes on a 64 bit machine, which "masks" the issue. Compiling for 32 bit reveals the issue more clearly.
Fix the typo for correctness, and to make the code robust to future evolutions of the skl_ipc_dxstate_info structure size.
This fixes the following coccicheck error:
sound/soc/intel/skylake/skl-sst-ipc.c:641:8-14: ERROR: application of sizeof to pointer
