this patch in next-20181214 breaks "make modules_install" for arm64/defconfig on my Ubuntu machine:

DEPMOD 4.20.0-rc6-next-20181214
depmod: ERROR: Found 6 modules in dependency cycles!
depmod: ERROR: Cycle detected: caamalg_desc -> dpaa2_caam -> authenc
depmod: ERROR: Cycle detected: caamalg_desc -> dpaa2_caam -> fsl_mc_dpio

depmod: ERROR: Cycle detected: caamalg_desc -> dpaa2_caam -> caamhash_desc -> error
depmod: ERROR: Cycle detected: caamalg_desc -> dpaa2_caam -> caamhash_desc -> caamalg_desc

After reverting of this patch the issue disappeared.
