The patch titled
isapnp: handle independent options following dependent ones
has been removed from the -mm tree. Its filename was
isapnp-handle-independent-options-following-dependent-ones.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: isapnp: handle independent options following dependent ones
From: Bjorn Helgaas <bjorn.helgaas@xxxxxx>
The ISAPNP spec recommends that independent options precede dependent
ones, but this is not actually required. The current ISAPNP code
incorrectly puts such trailing independent options at the end of the last
dependent option list.
This patch fixes that bug by resetting the current option list to the
independent list when we see an "End Dependent Functions" tag. PNPBIOS
and PNPACPI handle this the same way.
