In the Makefile, the new build option CONFIG_CAAM_QI is defined conditioned on the existence of the CONFIG_CRYPTO_DEV_FSL_CAAM_CRYPTO_API_QI, which is properly defined in the Kconfig file. So, CONFIG_CAAM_QI is just a local alias for CONFIG_CRYPTO_DEV_FSL_CAAM_CRYPTO_API_QI. There is little benefit in the source code of having this slightly shorter alias for this configuration, but it complicates further maintenance, as searching for the impact of CONFIG_CRYPTO_DEV_FSL_CAAM_CRYPTO_API_QI requires to grep once, and then identify the option introduced and continue searching for that. Further, tools, such as cross referencers, and scripts to check Kconfig definitions and their use simply do not handle this situation. Given that this is the only incidence of such a config alias in the whole kernel tree, just prefer to avoid this pattern of aliasing here. Use CONFIG_CRYPTO_DEV_FSL_CAAM_CRYPTO_API_QI throughout the Freescale CAAM-Multicore platform driver backend source code. No functional change.
