Changes in v12:
- clear the ctx->need_fallback flag for key sizes other than AES-192
  (sashiko)
- Link to v11: https://patch.msgid.link/20261019-qce-fixes-aead-v11-0-11c55cc7a695@oss.qualcomm.com

Changes in v11:
- Split out the aead patches into a smaller series for easier review
- add a patch fixing a race condition resulting from sharing
  ctx->eed_fallback by concurrent requests
- Link to v10: https://patch.msgid.link/20261013-qce-fix-self-tests-v10-0-57162a38a554@oss.qualcomm.com

Changes in v10:
- don't pass a NULL buffer to sg_init_one()
- fix byte order of the imported hash state on empty finalization
- don't recompute the CTR counter in software for every request
- reject skcipher requests with a too short scatterlist
- check fragmentation for empty CCM decryption requests too
- don't use a static loop iterator (duh...)
- initialize the return value in qce_handle_queue()
- Link to v9: https://patch.msgid.link/20260922-qce-fix-self-tests-v9-0-b1aa742e79af@oss.qualcomm.com

Changes in v8:
- Add a patch making the crypto driver *not* register algos by default
  but only if the user explicitly requests it with the provided module
  parameter
- Use the "offloader" name for the crypto IP instead of "accelerator"
- Fix device module table issues
- Make the core driver use a list (despite it only having a single
  member now) of child auxiliary devices to register to make it clear we
  have the intention of extending this once we start the work on secure
  media playback
- Link to v7: https://patch.msgid.link/20260910-qce-fix-self-tests-v7-0-cdbd2718af14@oss.qualcomm.com

  auxiliary device and removing the BROKEN Kconfig label

Changes in v6:
- Handle all zero-length HMAC finalizations (like imported state with
  data already hashed), not only the genuinely empty message case
- Add an additional patch addressing the fragmented skcipher payload
  issue
- Link to v5: https://patch.msgid.link/20260706-qce-fix-self-tests-v5-0-86f461ff1829@oss.qualcomm.com
