The patch titled
tty: Clarify documentation of ->write()
has been removed from the -mm tree. Its filename was
tty-clarify-documentation-of-write.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: tty: Clarify documentation of ->write()
From: Alan <alan@xxxxxxxxxxxxxxxxxxx>
