* Drivers: crypto: remove __dev* attributes.Greg Kroah-Hartman2013-01-031-3/+3
| | | | | | | | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

Attached patch should not allow HIFN to be registered on 64-bit arch, so crypto layer will fallback to the software algorithms.

| | | | | | | | | | HIFN uses little-endian by default, move cpu_to_le32 conversion to hifn_write_0/ hifn_write_1, add sparse annotations and fix an invalid endian conversion in hifn_setup_src_desc.

* [CRYPTO] hifn795x: Disallow built-in hifn795x when HW_RANDOM is mHerbert Xu2008-01-261-3/+3
| | | | | | | | | | | Currently it is possible to select HW_RANDOM as a module and have hifn795x built-in. This causes a build problem because hifn795x will then call hwrng_register which isn't built-in. This patch introduces a new config option to control the hifn795x RNG which lets us avoid this problem. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
