The patch titled
Subject: various: fix pci_set_dma_mask return value checking
has been removed from the -mm tree. Its filename was
various-fix-pci_set_dma_mask-return-value-checking.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Christoph Hellwig <hch@xxxxxx>
Subject: various: fix pci_set_dma_mask return value checking
pci_set_dma_mask returns a negative errno value, not a bool like
pci_dma_supported. This of course was just a giant test for attention :)
