iommu/vt-d: Convert non-returned local variable to boolean when relevant
This patch was produced using Coccinelle. A simplified version of the semantic patch is: @r exists@ identifier f; local idexpression u8 x; identifier xname; @@ f(...) { ...when any ( x@xname = 1; | x@xname = 0; ) ...when any } @bad exists@ identifier r.f; local idexpression u8 r.x expression e1 != {0, 1}, e2; @@ f(...) { ...when any ( x = e1; | x + e2 ) ...when any } @depends on !bad@ identifier r.f; local idexpression u8 r.x; identifier r.xname; @@ f(...) { ... ++ bool xname; - int xname; <... ( x = - 1 + true | x = - -1 + false ) ...> } Signed-off-by: Quentin Lambert <lambert.quentin@gmail.com> Signed-off-by: Joerg Roedel <jroedel@suse.de>
