The patch titled
s3c2410fb: remove fb_info pointer from s3c2410fb_info
has been removed from the -mm tree. Its filename was
s3c2410fb-remove-fb_info-pointer-from-s3c2410fb_info.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: s3c2410fb: remove fb_info pointer from s3c2410fb_info
From: Krzysztof Helt <krzysztof.h1@xxxxx>
This patch removes redundant fb field from
the s3c2410fb_info structure. This breaks circular
reference fb_info -> s3c2410fb_info -> fb_info again.
