Subject: [PATCH 3/3] PCI: microchip: Remove cast between incompatible function type
Date: Thu, 29 Jun 2023 16:59:56 +0000 [thread overview]
Message-ID: <20230629165956.237832-3-kwilczynski@kernel.org> (raw)
In-Reply-To: <20230629165956.237832-1-kwilczynski@kernel.org>
Rather than casting void(*)(struct clk *) to void (*)(void *), that
forces conversion to an incompatible function type, replace the cast
with a small local stub function with a signature that matches what
the devm_add_action_or_reset() function expects.
The sub function takes a void *, then passes it directly to
clk_disable_unprepare(), which handles the more specific type.
Reported by clang when building with warnings enabled:
drivers/pci/controller/pcie-microchip-host.c:866:32: warning: cast from 'void (*)(struct clk *)' to 'void (*)(void *)' converts to incompatible function type [-Wcast-function-type-strict]
devm_add_action_or_reset(dev, (void (*) (void *))clk_disable_unprepare,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
No functional changes are intended.
