    Subject[PATCH 5.4 102/475] crypto: vmx - add missing dependencies
    Date
    From: Petr Vorel <pvorel@suse.cz>

    [ Upstream commit 647d41d3952d726d4ae49e853a9eff68ebad3b3f ]

    vmx-crypto module depends on CRYPTO_AES, CRYPTO_CBC, CRYPTO_CTR or
    CRYPTO_XTS, thus add them.

    These dependencies are likely to be enabled, but if
    CRYPTO_DEV_VMX=y && !CRYPTO_MANAGER_DISABLE_TESTS
    and either of CRYPTO_AES, CRYPTO_CBC, CRYPTO_CTR or CRYPTO_XTS is built
    as module or disabled, alg_test() from crypto/testmgr.c complains during
    boot about failing to allocate the generic fallback implementations
    (2 == ENOENT):

    [ 0.540953] Failed to allocate xts(aes) fallback: -2
    [ 0.541014] alg: skcipher: failed to allocate transform for p8_aes_xts: -2
    [ 0.541120] alg: self-tests for p8_aes_xts (xts(aes)) failed (rc=-2)
    [ 0.544440] Failed to allocate ctr(aes) fallback: -2
    [ 0.544497] alg: skcipher: failed to allocate transform for p8_aes_ctr: -2
    [ 0.544603] alg: self-tests for p8_aes_ctr (ctr(aes)) failed (rc=-2)
    [ 0.547992] Failed to allocate cbc(aes) fallback: -2
    [ 0.548052] alg: skcipher: failed to allocate transform for p8_aes_cbc: -2
    [ 0.548156] alg: self-tests for p8_aes_cbc (cbc(aes)) failed (rc=-2)
    [ 0.550745] Failed to allocate transformation for 'aes': -2
    [ 0.550801] alg: cipher: Failed to load transform for p8_aes: -2
    [ 0.550892] alg: self-tests for p8_aes (aes) failed (rc=-2)

    Fixes: c07f5d3da643 ("crypto: vmx - Adding support for XTS")
    Fixes: d2e3ae6f3aba ("crypto: vmx - Enabling VMX module for PPC64")
