The patch titled
arch/mips/alchemy: correct code taking the size of a pointer
has been removed from the -mm tree. Its filename was
arch-mips-alchemy-correct-code-taking-the-size-of-a-pointer.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: arch/mips/alchemy: correct code taking the size of a pointer
From: Julia Lawall <julia@xxxxxxx>
sizeof(dp) is just the size of the pointer. Change it to the size of the
referenced structure.
A simplified version of the semantic patch that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
expression *x;
expression f;
type T;
@@
*f(...,(T)x,...)
// </smpl>
