iio: sc27xx_adc: Use DIV_ROUND_CLOSEST() instead of open-coding it
Use DIV_ROUND_CLOSEST() instead of open-coding it. This makes it more clear what is going on for the casual reviewer. Generated using the following the Coccinelle semantic patch. // <smpl> @@ expression x, y; @@ -((x) + ((y) / 2)) / (y) +DIV_ROUND_CLOSEST(x, y) // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Acked-by: Chunyan Zhang <zhang.lyra@gmail.com> Link: https://lore.kernel.org/r/20201222191618.3433-1-lars@metafoo.de Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
