Subject: [PATCH v10 09/25] crypto: iaa - Deprecate exporting add/remove IAA compression modes.
Date: Thu,  3 Jul 2025 21:23:07 -0700	[thread overview]
Message-ID: <20250704042323.10318-10-kanchana.p.sridhar@intel.com> (raw)
In-Reply-To: <20250704042323.10318-1-kanchana.p.sridhar@intel.com>

There is no use case right now for kernel users to dynamically
add/remove IAA compression modes; hence this commit deletes the symbol
exports of add_iaa_compression_mode() and remove_iaa_compression_mode().

The only supported usage model of IAA compression modes is for the code
to be statically linked during the iaa_crypto module build,
e.g. iaa_crypto_comp_fixed.c, and for available modes to be registered
when the first IAA device wq is probed.
