From c2a90eee29f41630225c9a64d26c425e1d50b401 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Mon, 8 Jul 2024 16:53:25 -0700 Subject: scsi: ufs: core: Add UFSHCD_QUIRK_CUSTOM_CRYPTO_PROFILE Add UFSHCD_QUIRK_CUSTOM_CRYPTO_PROFILE which lets UFS host drivers initialize the blk_crypto_profile themselves rather than have it be initialized by ufshcd-core according to the UFSHCI standard. This is needed to support inline encryption on the "Exynos" UFS controller which has a nonstandard interface.
