Subject: [PATCH 3.13 081/149] spi: coldfire-qspi: Fix getting correct address for *mcfqspi

3.13-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Axel Lin <axel.lin@...ics.com>

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)
