[PATCH v2 1/2] Bluetooth: Remove unneeded crypto kconfig selections
From: Eric Biggers
Date: Tue Apr 21 2026 - 19:11:40 EST
Remove several kconfig selections that are no longer needed:
- CRYPTO_SKCIPHER and CRYPTO_ECB have been unneeded since
commit a4770e1117f1 ("Bluetooth: Switch SMP to
crypto_cipher_encrypt_one()") in 2016.
- CRYPTO_SHA256 has been unneeded since
commit e7b02296fb40 ("Bluetooth: Remove BT_HS") in 2024.
