commitc84117912bupstream. lpc32xx_udc_probe() acquires an i2c_client reference through isp1301_get_client() but fails to release it in both error handling paths and the normal removal path. This could result in a reference count leak for the I2C device, preventing proper cleanup and potentially leading to resource exhaustion. Add put_device() to release the reference in the probe failure path and in the remove function. Calling path: isp1301_get_client() -> of_find_i2c_device_by_node() -> i2c_find_device_by_fwnode(). As comments of i2c_find_device_by_fwnode() says, 'The user must call put_device(&client->dev) once done with the i2c client.' Found by code review.
