[Verification] Linux JAMMY linux-bluefield/5.15.0-1076.78 Tested on a BF3220 Bluefield-3 model
After the upgrade to version 1076.78, the driver is correctly loaded, no error messages could be observed. Successfully verified the pinctrl module is initialized. Booted multiple times, the system remains stable with no error messages and proper initialization.

This critical driver structure should make use of this technique for improved stability. [Fix] The fix is to cherry pick the following upstream patch: 490bfd1ca556 pinctrl: Constify static 'pinctrl_desc' It may be required to cherry pick other upstream patches so that everything applies cleanly. [Test Case] * Boot BlueField-3 platform with software containing fix * Verify that pinctrl-mlxbf3 modules is loaded properly * Check the kernel log via dmesg for proper messages from pinctrl subsystem * Verify that there are no kernel faults caused by pinctrl-mlxbf3 * Reboot several times and keep checking log [Regression Potential] This fix is upstreamed and tested well.
