Subject: xen/grant-table: Fix incorrect gnttab_dma_free_pages() pr_debug message
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=d9cccfa7c4d1d9ef967ec9308df7304a18609b30;p=openwrt%2Fstaging%2Fblogic.git

xen/grant-table: Fix incorrect gnttab_dma_free_pages() pr_debug message

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')
