[PATCH] ASoC: samsung: Constify snd_soc_dapm_{route,widget} structs
These structs only have their address assigned to the dapm_{routes,widget} fields in the snd_soc_card struct, both which are pointers to const data. Make them const to allow the compiler to put them in read-only memory.

Thanks!
[1/1] ASoC: samsung: Constify snd_soc_dapm_{route,widget} structs commit: 5449fd7bd01fc13266979a6ab48493d4d2e43725
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
