Subject: [PATCH] pcmcia: Use setup_timer and mod_timer

This patch introduces the use of functions setup_timer
and mod_timer.

This is done using Coccinelle and semantic patch used
for this as follows:

// <smpl>
@@
expression x,y,z,a,b;
@@

-init_timer (&x);
+setup_timer (&x, y, z);
+mod_timer (&a, b);
-x.function = y;
-x.data = z;
-x.expires = b;
-add_timer(&a);

// </smpl>
