The patch titled
Add struct dev pointer to dma_is_consistent()
has been removed from the -mm tree. Its filename was
add-struct-dev-pointer-to-dma_is_consistent.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Add struct dev pointer to dma_is_consistent()
From: Ralf Baechle <ralf@xxxxxxxxxxxxxx>
dma_is_consistent() is ill-designed in that it does not have a struct
device pointer argument which makes proper support for systems that consist
of a mix of coherent and non-coherent DMA devices hard. Change
dma_is_consistent to take a struct device pointer as first argument and fix
the sole caller to pass it.
