From: Jack Morgenstein Date: Mon, 28 Jul 2014 20:30:23 +0000 (+0300) Subject: mlx5: minor fixes (mainly avoidance of hidden casts) X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=f241e7497ec2d22b83002b17ae91a851d4034cb7;p=openwrt%2Fstaging%2Fblogic.git mlx5: minor fixes (mainly avoidance of hidden casts) 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).
