-Subject: [PATCH 1/6] crypto: crypto4xx - shuffle iomap in front of request_irq
-
-It is possible to avoid the ce_base null pointer check in the
-drivers' interrupt handler routine "crypto4xx_ce_interrupt_handler()"
-by simply doing the iomap in front of the IRQ registration.
-
-This way, the ce_base will always be valid in the handler and
-a branch in an critical path can be avoided.
