+Subject: [PATCH] Revert "integrity: Only use machine keyring when
+ uefi_check_trust_mok_keys is true"
+
+This reverts commit 3d6ae1a5d0c2019d274284859f556dcb64aa98a7.
+
+MokListTrustedRT doesn't seem to be set by the Shim version used by
+Ubuntu and Debian. Therefore, these systems don't trust the MOK keys on
+newer kernels. While pre-5.19 kernels silently disregard the untrusted
+keys and (without signature enforcement enabled) still load external
+modules (tainting the kernel), on 5.19 kernels, this breaks module
+loading. Therefore, revert this change.
+
+See https://github.com/linux-surface/linux-surface/issues/906.
