Signed-off-by: Naveen Krishna Chatradhi ch.nav...@samsung.com Reviewed-by: Doug Anderson diand...@chromium.org Applied to the togreg branch of iio.git I wasn't sure if this one was technically a fix, but as it isn't marked clearly as such it can go in during the next merge window. I won't have pushed this out to a non rebasing branch until tomorrow so if this fixes an observed issue then let me know and it might move to the fixes-togreg branch.

As far as I know this doesn't fix an observed issue. I believe it was requested as part of a previous review and is finally reposted. I believe it's just extra precautions to make sure that some old IRQ didn't accidentally complete us between the last transaction and this one. Old discussion is somewhere around here https://patchwork.kernel.org/patch/2279591/ Thanks! -Doug -- To unsubscribe from this list: send the line unsubscribe linux-samsung-soc in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
