The patch titled
Subject: drivers/net/ethernet/amd/pcnet32.c: neaten and remove unnecessary OOM messages
has been removed from the -mm tree. Its filename was
amd-neaten-and-remove-unnecessary-oom-messages.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Joe Perches <joe@xxxxxxxxxxx>
Subject: drivers/net/ethernet/amd/pcnet32.c: neaten and remove unnecessary OOM messages
Make the code flow a little better for 80 columns.
Use a consistent style for the RX and TX rings allocation.
Use BIT macro.
Use a temporary unsiged int entries for (1<<size).
Remove the OOM messages as they duplicate the generic
OOM and dump_stack() provided by the memory subsystem.
Reflow allocs to 80 columns.
