ALSA: emu10k1: Use DIV_ROUND_UP() instead of open-coding it
Use DIV_ROUND_UP() instead of open-coding it. This documents intent and 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) - 1) / (y)) +DIV_ROUND_UP(x, y) // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Link: https://lore.kernel.org/r/20201223172229.781-8-lars@metafoo.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
