From: Arnd Bergmann Subject: [PATCH] crypto: cavium: fix Kconfig dependencies Date: Tue, 14 Feb 2017 18:07:31 +0100 Message-ID: <20170214170739.2687818-1-arnd@arndb.de> Cc: Arnd Bergmann , David Daney , linux-crypto@vger.kernel.org, linux-kernel@vger.kernel.org To: George Cherian , Herbert Xu , "David S. Miller" Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: linux-crypto.vger.kernel.org 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' struct msix_entry msix_entries[CPT_PF_MSIX_VECTORS]; ^~~~~~~~~~~~ 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.
