crypto: cavium - switch to pci_alloc_irq_vectors

2017-02-23T12:11:02+00:00

pci_enable_msix has been long deprecated, but this driver adds a new
instance.  Convert it to pci_alloc_irq_vectors and greatly simplify
the code, and make sure the prope code properly unwinds.

crypto: cavium - fix Kconfig dependencies

2017-02-15T05:23:50+00:00

The driver fails to build if MSI support is disabled:

In file included from /git/arm-soc/drivers/crypto/cavium/cpt/cptpf_main.c:18:0:
drivers/crypto/cavium/cpt/cptpf.h:57:20: error: array type has incomplete element type 'struct msix_entry'

                    ^~~~~~~~~~~~
drivers/crypto/cavium/cpt/cptpf_main.c: In function 'cpt_enable_msix':
drivers/crypto/cavium/cpt/cptpf_main.c:344:8: error: implicit declaration of function 'pci_enable_msix';did you mean 'cpt_enable_msix'? [-Werror=implicit-function-declaration]

On the other hand, it doesn't seem to have any build dependency on ARCH_THUNDER,
so let's allow compile-testing to catch this kind of problem more easily.
The 64-bit dependency is needed for the use of readq/writeq.

cpt_bind_vq_to_grp() could return an error code. However, it currently
returns a u8. This produce the static checker warning.
