From: Herton Ronaldo Krzesinski Date: Fri, 11 May 2012 22:29:50 +0000 (-0700) Subject: spi/spi-fsl-spi: reference correct pdata in fsl_spi_cs_control X-Git-Tag: firefly_0821_release~7541^2~608 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=81e80587f3fc5239bdcdcb69750e24448485d7f6;p=firefly-linux-kernel-4.4.55.git spi/spi-fsl-spi: reference correct pdata in fsl_spi_cs_control commit 067aa4815a9bc12a569d8a06afef50ba5773afbf upstream. 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.
