From 6469933605a3ecdfa66b98160cde98ecd256cb3f Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Mon, 4 Jun 2012 12:44:16 +0000 Subject: ethernet: Remove casts to same type Adding casts of objects to the same type is unnecessary and confusing for a human reader. For example, this cast: int y; int *p = (int *)&y; I used the coccinelle script below to find and remove these unnecessary casts. I manually removed the conversions this script produces of casts with __force, __iomem and __user. @@ type T; T *p; @@ - (T *)p + p A function in atl1e_main.c was passed a const pointer when it actually modified elements of the structure. Change the argument to a non-const pointer. A function in stmmac needed a __force to avoid a sparse warning. Added it. Signed-off-by: Joe Perches Signed-off-by: David S.
