[alsa-devel] [PATCH 1/16 v2] sound/soc/pxa/mioa701_wm9713.c: Avoid using ARRAY_AND_SIZE(e) as a function argument

From: Julia Lawall <Julia.Lawall at lip6.fr>

Replace ARRAY_AND_SIZE(e) in function argument position to avoid hiding the
arity of the called function.

At the suggestion of Robert Jarzmik, this additionally removes the
definition of ARRAY_AND_SIZE, which is not used elsewhere in the file.

The semantic match that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
expression e,f;
@@

f(...,
- ARRAY_AND_SIZE(e)
+ e,ARRAY_SIZE(e)
  ,...)
// </smpl>

Signed-off-by: Julia Lawall <Julia.Lawall at lip6.fr>

Not compiled.
v2 removes the definition of ARRAY_AND_SIZE.
