[BUG] blacklist: Problem blacklisting hash (-13) during boot

[Thomas Weißschuh]

Hi,

Since 5.19 during boot I see lots of the following entries in dmesg:

blacklist: Problem blacklisting hash (-13)

This happens because the firmware contains duplicate blacklist entries.
As commit 6364d106e041 [0] modified the "blacklist" keyring to reject updates
this now leads to the spurious error messages.

The machine is a Thinkpad X1 Cargon Gen9 with BIOS revision 1.56 and firmware
revision 1.33.
