[PATCH -next] uio: pruss: fix missing iounmap() in pruss_probe()

From: Yang Yingliang
Date: Tue Aug 08 2023 - 16:42:55 EST


platform_get_irq() is called after ioremap(), if it fails,
iounmap() needs be called in error the path.

Fixes: 2fd84b9b839c ("uio: pruss: fix to check return value of platform_get_irq() in pruss_probe()")
