[PATCH 6.18 118/175] hwmon: (dell-smm) Add Dell G15 5510 to fan control whitelist

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.18-stable review patch.  If anyone has any objections, please let me know.

[ 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.
