commit 6216f5e6795f6aec3578b4387a05976e6d804327
Author: DC-SWAT <sw...@21...>
Date:   Sun Nov 16 23:23:51 2025 +0700

    g1ata: Do not switch the bus to Master on NAOMI.
    There is no need to switch to the master device (no syscalls for GD-ROM) on NAOMI, and by some reason this causes issues in the operation of the slave device.
