If you *must* share the variable between interrupt and non-interrupt context, you must mutex it in an interrupt safe way. The use of spin_lock_irqsave() comes to mind for you read function. But you are going to have other problems with this approach anyways since you "appear" to be assuming a one-to-one relationship between your interrupt handler and the read function.
