The patch titled
EHCI: fix memory pool name allocation
has been removed from the -mm tree. Its filename was
fix-gregkh-usb-ehci-hcd-fix-budget_pool-allocation-for-machines-with-multiple-ehci-controllers.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: EHCI: fix memory pool name allocation
From: Alan Stern <stern@xxxxxxxxxxxxxxxxxxx>
This patch (as802) changes the poolname allocation for the shadow budget in
ehci-mem.c. The name needs to be allocated dynamically, not on the stack,
because the memory management system continues to use it after
registration.
Also included are a couple of minor whitespace fixups (tabs instead of
spaces).
