3.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Axel Lin <axel.lin@xxxxxxxxxx>
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.
