crypto: bfin_crc - reposition free_irq to avoid access to invalid data
The data referenced by an interrupt handler should not be freed before the
interrupt is ended. The handler is bfin_crypto_crc_handler. It may refer
to crc->regs, which is released by the iounmap.
Furthermore, the second argument to all calls to free_irq is incorrect. It
should be the same as the last argument of request_irq, which is crc,
rather than crc->dev.
The semantic match that finds the first problem is as follows:
