2015-08-13crypto: caam - Remove unneeded 'ret' variableFabio Estevam1-2/+2
Variable 'ret' is only used for returning the value 0. We can make it simpler and just return 0 instead.

2015-08-10crypto: talitos - Prevent panic in probe error pathAaron Sierra2-2/+12
The probe error path for this driver, for all intents and purposes, is the talitos_remove() function due to the common "goto err_out". Without this patch applied, talitos_remove() will panic under these two conditions: 1. If the RNG device hasn't been registered via talitos_register_rng() prior to entry into talitos_remove(), then the attempt to unregister the RNG "device" will cause a panic. 2. If the priv->chan array has not been allocated prior to entry into talitos_remove(), then the per-channel FIFO cleanup will panic because of the dereference of that NULL "array". Both of the above scenarios occur if talitos_probe_irq() fails. This patch resolves issue #1 by introducing a boolean to mask the hwrng_unregister() call in talitos_unregister_rng() if RNG device registration was unsuccessful. It resolves issue #2 by checking that priv->chan is not NULL in the per-channel FIFO cleanup for loop.

It's unlikely that the caller will use the compressed data since it's larger than the original uncompressed data, but there was no error and returning an error code is incorrect.

2015-07-23crypto: nx - make platform drivers directly register with cryptoDan Streetman6-191/+114
Remove the common 'platform' registration module, and move the crypto compression driver registration into each of the pSeries and PowerNV platform NX 842 drivers. Change the nx-842.c code into simple common functions that each platform driver uses to perform constraints-based buffer changes, i.e. realigning and/or resizing buffers to match the driver's hardware requirements. The common 'platform' module was my mistake to create - since each platform driver will only load/operate when running on its own platform (i.e. a pSeries platform or a PowerNV platform), they can directly register with the crypto subsystem, using the same alg and driver name.
