struct atomisp_platform_data only has a single subdevs member. Remove this struct and replace atomisp_get_platform_data() with atomisp_platform_get_subdevs(). Note atomisp_get_platform_data() and now atomisp_platform_get_subdevs() always succeed, so while at it also remove unnecessary error checking.
