4.19-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit d9cccfa7c4d1d9ef967ec9308df7304a18609b30 ]
If a call to xenmem_reservation_increase() in gnttab_dma_free_pages()
fails it triggers a message "Failed to decrease reservation..." which
should be "Failed to increase reservation..."
Fixes: 9bdc7304f536 ('xen/grant-table: Allow allocating buffers suitable for DMA')
