commit 662a9ece32 upstream.
When the USB5744 option is disabled, the onboard_usb driver warns about
unused functions:
drivers/usb/misc/onboard_usb_dev.c:358:12: error: 'onboard_dev_5744_i2c_write_byte' defined but not used [-Werror=unused-function]
358 | static int onboard_dev_5744_i2c_write_byte(struct i2c_client *client, u16 addr, u8 data)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/usb/misc/onboard_usb_dev.c:313:12: error: 'onboard_dev_5744_i2c_read_byte' defined but not used [-Werror=unused-function]
313 | static int onboard_dev_5744_i2c_read_byte(struct i2c_client *client, u16 addr, u8 *data)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Extend the #ifdef block a little further to cover all of these functions.
Ideally we'd use use if(IS_ENABLED()) instead, but that doesn't currently
work because the i2c_transfer() and i2c_smbus_write_word_data() function
declarations are hidden when CONFIG_I2C is disabled.
