Subject: spi: coldfire-qspi: Fix getting correct address for *mcfqspi
From: Axel Lin <axel.lin@xxxxxxxxxx>
commit ee73b4c6e3fc0755a91752ab8eebc8e070038b53 upstream.
dev_get_drvdata() returns the address of master rather than mcfqspi.
Fixes: af361079 (spi/coldfire-qspi: Drop extra calls to spi_master_get in suspend/resume functions)
