In tps65910_i2c_probe(), a dummy I2C transfer is performed to work around silicon erratum SWCZ010. However, the return value of i2c_master_send() is not checked. If this dummy transfer fails, the driver continues execution without detecting the error. This may lead to subsequent I2C operations also failing, but the driver would incorrectly report success. Add proper return value checking for the dummy I2C transfer. If the transfer fails, log the error and return an appropriate error code to the caller.
