firmware: dmi-id: add a release callback function
[ Upstream commit cf770af5645a41a753c55a053fa1237105b0964a ]
dmi_class uses kfree() as the .release function, but that now causes
a warning with clang-16 as it violates control flow integrity (KCFI)
rules:
drivers/firmware/dmi-id.c:174:17: error: cast from 'void (*)(const void *)' to 'void (*)(struct device *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict]
174 | .dev_release = (void(*)(struct device *)) kfree,
Add an explicit function to call kfree() instead.
Fixes: 4f5c791a850e ("DMI-based module autoloading")
