From 36b81af9e8ecea2bf58aae9a421720ed10f61b82 Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Thu, 1 Dec 2016 01:02:44 -0800 Subject: spi: Pass pointer to spi_slave structure in spi_setup_slave For spi_setup_slave, instead of making the platform driver return a pointer to spi_slave structure, pass in a structure pointer that can be filled in by the driver as required. This removes the need for platform drivers to maintain a slave structure in data/CAR section.
