[PATCH 6.18 094/333] net: dsa: realtek: Fix LED group port bit for non-zero LED group

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

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

------------------

From: Marek Behún <kabel@kernel.org>

[ Upstream commit e8f0dc024ce55451ebd54bad975134ba802e4fcc ]

The rtl8366rb_led_group_port_mask() function always returns LED port
bit in LED group 0; the switch statement returns the same thing in all
non-default cases.

This means that the driver does not currently support configuring LEDs
in non-zero LED groups.

Fix this.
