Date: Tue, 9 Aug 2022 11:29:43 -0700	[thread overview]
Message-ID: <20220809112943.393684af@hermes.local> (raw)

commit 23d99baf9d729ca30b2fb6798a7b403a37bfb800
Author: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
Date:   Tue Apr 19 13:34:28 2022 +0200

    PCI: Use driver_set_override() instead of open-coding
    
    Use a helper to set driver_override to the reduce amount of duplicated
    code.  Make the driver_override field const char, because it is not
    modified by the core and it matches other subsystems.

The script is sending single nul character to remove override
and that no longer works.
