Subject[PATCH] ASoC: stm32: sai: fix less than zero comparison on unsigned int
Date
From: Colin Ian King <colin.king@canonical.com>

Currently, the comparison of div < 0 is always false because div is
an unsigned int. Fix this by making div an int.

Detected by CoverityScan, CID#1475309 ("Unsigned compared against 0")

Fixes: 8307b2afd386 "(ASoC: stm32: sai: set sai as mclk clock provider")
