[PATCH 04/11] phy: exynos-mipi-video: fix check on array index

[Kishon Vijay Abraham I]

From: Antoine TÃnart <antoine.tenart@xxxxxxxxxxxxxxxxxx>

The phys array is of size EXYNOS_MIPI_PHYS_NUM. Trying to access the
index EXYNOS_MIPI_PHYS_NUM should return an error.

Fixes: 069d2e26e9d6 "phy: Add driver for Exynos MIPI CSIS/DSIM DPHYs"
