Subject: drivers/video/exynos/exynos_mipi_dsi.c: fix an error check condition
Checking an unsigned variable for negative value returns false. Hence use
the macro to fix it.
Fixes the following smatch warning:
drivers/video/exynos/exynos_mipi_dsi.c:417 exynos_mipi_dsi_probe() warn:
unsigned 'dsim->irq' is never less than zero.
