From d790c342e689ea77a5cf72d5b993299911ee5276 Mon Sep 17 00:00:00 2001 From: Emil Renner Berthing Date: Wed, 31 Oct 2018 11:57:05 +0100 Subject: spi: rockchip: remove master pointer from dev data In almost all cases we already have a pointer to the spi master structure where we have the driver data. The only exceptions are the dma callbacks which are easily fixed by passing them the master and using spi_master_get_devdata to retrieve the driver data.
