[MIPS] 0 -> NULL
When comparing a pointer, it's clearer to compare it to NULL than to 0. Here is an excerpt of the semantic patch: @@ expression *E; @@ E == - 0 + NULL @@ expression *E; @@ E != - 0 + NULL Signed-off-by: Yoann Padioleau <padator@wanadoo.fr> Cc: ralf@linux-mips.org Cc: linux-mips@linux-mips.org Cc: akpm@linux-foundation.org Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
