The patch titled
drivers/misc/pti.c: give 'comm' function scope in pti_control_frame_built_and_sent()
has been removed from the -mm tree. Its filename was
drivers-misc-ptic-give-comm-function-scope-in-pti_control_frame_built_and_sent.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: drivers/misc/pti.c: give 'comm' function scope in pti_control_frame_built_and_sent()
From: Jesper Juhl <jj@xxxxxxxxxxxxx>
In drivers/misc/pti.c::pti_control_frame_built_and_sent() we assign 'comm'
to 'thread_name_p' if (!thread_name). The problem is that 'comm' then
goes out of scope and later we use 'thread_name_p' which now refers to an
out-of-scope variable. To fix that, simply move 'comm' up to have
function scope.
