Subject: [PATCH] hw/i2c/smbus_slave: Add object path on error prints
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

cheery-pick from fcc8299e29816c9b6f8d9766254fce6e8a50ee52

The current logging doesn't tell us which specific smbus device is an
error state.
