This is not a coccinelle bug. If it was, you would be patching
coccinelle, not the kernel.

Please google this, see the past discussion about why this code is
there.

I'd say the commit message is better than the commit ;)
Praghadeesh, could you fix Coccinelle to avoid matching:
if (/* case 1 */) {
/* BLOCK 1*/
} else (/* case 2 */ {
/* BLOCK 2 */
} else {
/* default == BLOCK 2 */
}
Because 99% of the time that construct is intentional.
