SRU Justification:

[Impact]

The BF3 GPIO driver (gpio-mlxbf3) in Jammy repo is missing an upstream patch.
The result is that kernel log shows this error message upon every boot:
    mlxbf3_gpio MLNXBF33:01: error -ENXIO: IRQ index 0 not found

[Fix]

The upstream patch "gpio: mlxbf3: use platform_get_irq_optional()"
needs to be cherry picked into Jammy repo.

[Test Case]

* Boot BF3 platform with software containing fix
* Check the kernel log via dmesg
* Verify no errors from BF3 GPIO driver related to "IRQ index 0"

[Regression Potential]
This fix is straightforward and present in upstream, so low risk.
