Nathan Chancellor f9af5ad0f5 vfio/cdx: Add parentheses between bitwise AND expression and logical NOT ... When building with clang, there is a warning (or error with CONFIG_WERROR=y) due to a bitwise AND and logical NOT in vfio_cdx_bm_ctrl(): drivers/vfio/cdx/main.c:77:6: error: logical not is only applied to the left hand side of this bitwise operator [-Werror,-Wlogical-not-parentheses] 77 | if (!vdev->flags & BME_SUPPORT) | ^ ~ drivers/vfio/cdx/main.c:77:6: note: add parentheses after the '!' to evaluate the bitwise operator first 77 | if (!vdev->flags & BME_SUPPORT) | ^ | ( ) drivers/vfio/cdx/main.c:77:6: note: add parentheses around left hand side expression to silence this warning 77 | if (!vdev->flags & BME_SUPPORT) | ^ | ( ) 1 error generated. Add the parentheses as suggested in the first note, which is clearly what was intended here.
