drivers/net: Correct redundant test
res has already been tested. It seems that this test should be on the recently returned value mmio. A simplified version of the semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r exists@ local idexpression x; expression E; @@ if (x == NULL || ...) { ... when forall return ...; } ... when != \(x=E\|x--\|x++\|--x\|++x\|x-=E\|x+=E\|x|=E\|x&=E\|&x\) ( *x == NULL | *x != NULL ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.
