The msm_gem_get_vaddr() returns an ERR_PTR() on failure, and a null
is catastrophic here, so we should use IS_ERR_OR_NULL() to check
the return value.

The mipi_dsi_device_register_full() returns an ERR_PTR() on failure,
we should use IS_ERR() to check the return value.
By the way, use dev_err_probe instead of dev_err to print the error code.
