Fixes use of word address as device address in i2c writes. Signed-off-by: Daniel Mangum <[email protected]>
Some callers pass a word address, but empty data buffer, when issuing i2c writes, such as when waking a device. Typically the HAL is passed a data buffer that includes the word address as the first byte, but when the data buffer is empty we opt to instead use the 1 byte word address as the data to be written.
