Subject: [patch] [IA64] fix SN_DMA_ADDRTYPE() condition
Date: Fri, 15 Jul 2016 21:12:15 +0000 [thread overview]
Message-ID: <20160715211215.GD19522@mwanda> (raw)
The parentheses are in the wrong place so it causes a static checker
warning. It means we don't mask away the high bits of dma_flags before
doing the comparison.
Fixes: 83821d3f558d ('[PATCH] PCI: altix: msi support')
