Pull driver core fixes from Danilo Krummrich: - Always inline I/O and IRQ methods using build_assert!() to avoid false positive build errors - Do not free the driver's device private data in I2C shutdown() avoiding race conditions that can lead to UAF bugs - Drop the driver's device private data after the driver has been fully unbound from its device to avoid UAF bugs from &Device<Bound> scopes, such as IRQ callbacks * tag 'driver-core-6.19-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core: rust: driver: drop device private data post unbind rust: driver: add DriverData type to the DriverLayout trait rust: driver: add DEVICE_DRIVER_OFFSET to the DriverLayout trait rust: driver: introduce a DriverLayout trait rust: auxiliary: add Driver::unbind() callback rust: i2c: do not drop device private data on shutdown() rust: irq: always inline functions using build_assert with arguments rust: io: always inline functions using build_assert with arguments
