[2/9] crypto: qat - change bufferlist logic interface

Commit Message

Cabiddu, Giovanni Aug. 18, 2022, 6:01 p.m. UTC

The functions qat_alg_sgl_to_bufl() and qat_alg_free_bufl() take as
argument a qat_crypto_instance and a qat_crypto_request structure.
These two structures are used only to get a reference to the
adf_accel_dev and qat_crypto_request_buffs.

In order to reuse these functions for the compression service, change
the signature so that they take adf_accel_dev and
qat_crypto_request_buffs.
