drivers: CCI: Correct use of ! and &
In commit ae91d60ba88ef0bdb1b5e9b2363bd52fc45d2af7, a bug was fixed that involved converting !x & y to !(x & y). The code below shows the same pattern, and thus should perhaps be fixed in the same way. The Coccinelle semantic patch that makes this change is as follows: // <smpl> @@ expression E1,E2; @@ ( !E1 & !E2 | - !E1 & E2 + !(E1 & E2) ) // </smpl> Signed-off-by: Himangi Saraogi <himangi774@gmail.com> Acked-by: Julia Lawall <julia.lawall@lip6.fr> Acked-by: Punit Agrawal <punit.agrawal@arm.com> Signed-off-by: Olof Johansson <olof@lixom.net>
