The patch titled
s3fb: do not allow incorrect pixclock settings
has been removed from the -mm tree. Its filename was
s3fb-do-not-allow-incorrect-pixclock-settings.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: s3fb: do not allow incorrect pixclock settings
From: Krzysztof Helt <[EMAIL PROTECTED]>
This patch adds check if selected pixclock is valid (is in the PLL range).
Previously, if the pixclock could not be set, the new mode resolution was set
but pixclock was not set which led to incorrect timings sent to monitor.
[adaplas]
Fixed a few misplaced curly braces.
