This code should be carefully reviewed, as this looks like the compiler
has highlighted a bug.  Based on the use of soc_private->cpas_handle
being passed to cam_cpas_reg_read in another translation unit,
drivers/media/platform/msm/camera_floral/cam_isp/isp_hw_mgr/isp_hw/vfe_hw/vfe_top/cam_vfe_camif_ver2.c
I suspect that they meant to use the first element's value, not the
address of the first element, truncated to 32b.
