[1/1] ASoC: wm5102: Use get_unaligned_be16() for dac_comp_coeff commit: 79405e3e5375875f8edc7dd6c1cf5376b1ded6e7 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

Replace the two-step copy-and-convert in wm5102_out_comp_coeff_put() with get_unaligned_be16(). Apart from looking nicer, it avoids this sparse warning: wm5102.c:687:35: sparse: sparse: cast to restricted __be16 Signed-off-by: Richard Fitzgerald <rf@opensource.cirrus.com> --- sound/soc/codecs/wm5102.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) base-commit: 2ebefde9de62a0828936e47b62975501993b5ee9
