The patch titled
FB/S3C2410: check default_display parameter passed in platform data
has been removed from the -mm tree. Its filename was
fb-s3c2410-check-default_display-parameter-passed-in-platform-data.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: FB/S3C2410: check default_display parameter passed in platform data
From: Ben Dooks <ben-linux@xxxxxxxxx>
Ensure that the default display parameter passed in via the
device's platform data is valid. It turns out when mach-bast.c
was updated, the default_display was set outside of the display
array bounds, causing a panic on startup.
If the default_display is bigger than num_displays, then generate
an error and refuse to initialise the driver.
