Add
15Q3EMS1.108to theCONF_G2_1firmware allow-list for the MSI Cyborg 15 B2RWEKG and B2RWGKG.Why
The firmware is currently rejected as unsupported, so
/sys/devices/platform/msi-ecis not created and applications such as MControlCenter cannot control performance, battery, or fan modes.The EC dump in #762 matches the
CONF_G2_1register layout, including shift mode at0xd2, fan mode at0xd4, charge control at0xd7, and cooler boost at0x98. The earlier MS-15Q3 report in #647 was also tested successfully by adding its firmware to the matching existing profile.Closes #762.
