Subject: [PATCH net-next 2/3] mlx5: minor fixes (mainly avoidance of hidden casts)
From: Jack Morgenstein <jackm@....mellanox.co.il>
There were many places where parameters which should be u8/u16 were
integer type.
Additionally, in 2 places, a check for a non-null pointer was added
before dereferencing the pointer (this is actually a bug fix).
