From e95881e0081a30e132b5ca087f1e07fc08608a7e Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Mon, 8 Jul 2024 16:53:27 -0700 Subject: scsi: ufs: core: Add UFSHCD_QUIRK_BROKEN_CRYPTO_ENABLE Add UFSHCD_QUIRK_BROKEN_CRYPTO_ENABLE which tells the UFS core to not use the crypto enable bit defined by the UFS specification. This is needed to support inline encryption on the "Exynos" UFS controller.
