Subject: [PATCH] ASoC: imx-pcm-rpmsg: Fix warning of incorrect type in assignment

The format in rpmsg is defained as unsigned char, there is warning
when convert snd_pcm_format_t to it.

sound/soc/fsl/imx-pcm-rpmsg.c:164:43: sparse: warning: incorrect type in assignment (different base types)
sound/soc/fsl/imx-pcm-rpmsg.c:164:43: sparse: expected unsigned char format
sound/soc/fsl/imx-pcm-rpmsg.c:164:43: sparse: got restricted snd_pcm_format_t [usertype]
sound/soc/fsl/imx-pcm-rpmsg.c:167:43: sparse: warning: incorrect type in assignment (different base types)
sound/soc/fsl/imx-pcm-rpmsg.c:167:43: sparse: expected unsigned char format
sound/soc/fsl/imx-pcm-rpmsg.c:167:43: sparse: got restricted snd_pcm_format_t [usertype]

Refine the unused RPMSG_DSD_U16_LE and RPMSG_DSD_U32_LE for these
case to fix this sparse warning.

Thanks!

[1/1] ASoC: imx-pcm-rpmsg: Fix warning of incorrect type in assignment
commit: a387040ab401cc114d0b1a7a86431c5ae34b163b

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
