[patch] crypto: caam - writel() arguments are swapped

From: Dan Carpenter <hidden>
Date: 2014-02-21 08:51:31
Also in: kernel-janitors
Subsystem: crypto api, freescale caam (cryptographic acceleration and assurance module) driver, the rest · Maintainers: Herbert Xu, "David S. Miller", Horia Geantă, Pankaj Gupta, Gaurav Jain, Linus Torvalds

My guess is that this little endian configuration is never found in real
life, but if it were then the writel() arguments are in the wrong order
so the driver would crash immediately.
