Subject[PATCH AUTOSEL 4.19 36/73] xen/grant-table: Fix incorrect gnttab_dma_free_pages() pr_debug message
Date
From: Liam Merwick <Liam.Merwick@oracle.com>

[ 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')
