If anyone has any objections, please let me know. ------------------ From: leobannocloutier@gmail.com [ Upstream commit 830e0bef79aaaea8b1ef426b8032e70c63a58653 ] On the Dell G15 5510, fans spin at maximum speed when AC power is connected. This behavior has been observed as a regression in recent kernels (v6.18+). Add the Dell G15 5510 to the fan control whitelist to enable manual fan control and resolve the issue. This model requires the same fan control configuration as the Dell G15 5511.
