From 067aa4815a9bc12a569d8a06afef50ba5773afbf Mon Sep 17 00:00:00 2001 From: Herton Ronaldo Krzesinski Date: Fri, 11 May 2012 15:29:50 -0700 Subject: spi/spi-fsl-spi: reference correct pdata in fsl_spi_cs_control Commit 178db7d3, "spi: Fix device unregistration when unregistering the bus master", changed spi device initialization of dev.parent pointer to be the master's device pointer instead of his parent. This introduced a bug in spi-fsl-spi, since its usage of spi device pointer was not updated accordingly. This was later fixed by commit 5039a86, "spi/mpc83xx: fix NULL pdata dereference bug", but it missed another spot on fsl_spi_cs_control function where we also need to update usage of spi device pointer. This change address that.
