Hi,   This patch should not be added to 6.1 stable since support for the Rockchip rv1126 SoC was only added later around 6.3.

The filename of the patch is: i2c-rk3x-adjust-mask-value-offset-for-i2c2-on-rv1126.patch and it can be found in the queue-6.1 subdirectory.

If you, or anyone else, feels it should not be added to the stable tree, please let stable@vger.kernel.org know about it.

commit 415eb64a74fe97dc85bcad99deaecfe57dce6b6a Author: Tim Lunn tim@feathertop.org Date: Sun Dec 3 23:39:59 2023 +1100

 i2c: rk3x: Adjust mask/value offset for i2c2 on rv1126
 
 [ Upstream commit 92a85b7c6262f19c65a1c115cf15f411ba65a57c ]
 
 Rockchip RV1126 is using old style i2c controller, the i2c2
 bus uses a non-sequential offset in the grf register for the
 mask/value bits for this bus.
 
 This patch fixes i2c2 bus on rv1126 SoCs.
