Resend to include mailing lists.

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.
