From: Axel Lin <[email protected]> This patch has been added to the 3.12 stable tree. If you have any objections, please let us know.
=============== commit 017145fef567430789e40f6a22a90ce2a766370b upstream. Current code set platform drvdata to dspi. However, the code in dspi_suspend() and dspi_resume() assumes the drvdata is the address of master. Fix it by setting platform drvdata to master.
