The patch titled
ATM: fix warning
has been removed from the -mm tree. Its filename was
atm-fix-warning.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: ATM: fix warning
From: Jeff Garzik <jeff@xxxxxxxxxx>
The compiler warning
drivers/atm/firestream.c: In function â??top_off_fpâ??:
drivers/atm/firestream.c:1505: warning: cast to pointer from integer of different size
does indicate a bug, albeit a minor one. Fixed, by using a 32-bit
temporary prior to the call to bus_to_virt().
The larger bug is still present: the entire driver assumes that machine
pointers are 32-bit, as it stores pointers in 32-bit hardware registers.
This is obvious to anyone who knows the driver well, but for the casual
readers it is helpfully noted with FIXME.
