From 6b27e27729270a2478fdebea2db9c4f57bb4e8e6 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Wed, 31 Oct 2018 19:31:43 +0000 Subject: [PATCH] ASoC: stm32: sai: fix less than zero comparison on unsigned int Currently, the comparison of div < 0 is always false because div is an unsigned int. Fix this by making div an int.
