Mariusz Kozlowski cc60d8baa3 drivers/ide/arm/icside.c: kmalloc + memset conversion to kzalloc
Is this a bug? In original verison memset cleared sizeof(state) bytes
instead of sizeof(*state). If it was intentional then this patch is invalid.
If not intentional -> valid :) Please review.

Bart: Yes, it is a bug so this patch is a valid bugfix. :-)
