6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Peter Griffin <peter.griffin@xxxxxxxxxx>
commit c662cedea14efdcf373d8d886ec18019d50e0772 upstream.
Move the EXYNOS_UFS_OPT_UFSPR_SECURE check inside
exynos_ufs_config_smu().
This way all call sites will benefit from the check. This fixes a bug
currently in the exynos_ufs_resume() path on gs101 as it calls
exynos_ufs_config_smu() and we end up accessing registers that can only
be accessed from secure world which results in a serror.
Fixes: d11e0a318df8 ("scsi: ufs: exynos: Add support for Tensor gs101 SoC")
