[PATCH 2/6] clk: exynos: Fix incorrect usage of IS_ERR_OR_NULL

[PATCH 2/6] clk: exynos: Fix incorrect usage of IS_ERR_OR_NULL

[Tony Prisk]

Replace IS_ERR_OR_NULL with IS_ERR on clk_get results.

In the fail: path of mixer_resources_init() and vp_resources_init()
the first clk tested cannot be NULL either, so IS_ERR_OR_NULL is
removed from these as well. Other clocks may still be NULL as they
haven't been clk_get'd yet.
