This patch series is a result of running kernel crypto fuzz tests (by
enabling CONFIG_CRYPTO_MANAGER_EXTRA_TESTS) on the transformations
currently supported via the Qualcomm crypto engine on sdm845. The first
four patches are fixes for various regressions found during testing. The
last two patches are minor clean ups of unused variable and parameters.

v2->v3:
- Made the comparison between keys to check if any two keys are
same for triple des algorithms constant-time as per
Nym Seddon's suggestion.
- Rebased to 5.11-rc4.
v1->v2:
- Introduced custom struct qce_sha_saved_state to store and restore
partial sha transformation.
- Rebased to 5.11-rc3.

Thara Gopinath (6):

as part of final
drivers: crypto: qce: skcipher: Fix regressions found during fuzz
testing
drivers: crypto: qce: common: Set data unit size to message length for
AES XTS transformation
