[PATCH AUTOSEL 6.6 12/15] ASoC: stm: Prevent potential division by zero in stm32_sai_mclk_round_rate()

[Sasha Levin]

From: Luo Yifan <luoyifan@cmss.chinamobile.com>

[ Upstream commit 63c1c87993e0e5bb11bced3d8224446a2bc62338 ]

This patch checks if div is less than or equal to zero (div <= 0). If
div is zero or negative, the function returns -EINVAL, ensuring the
division operation (*prate / div) is safe to perform.
