[fix] components: serial_v2: preserve RT_DEVICE_FLAG_STREAM when reopening serial device

2026-05-20T02:05:02Z

- The serial_fops_open function closes and reopens the serial device,but the RT_DEVICE_FLAG_STREAM flag was not preserved across the close/open cycle. This change saves the STREAM flag before close and restores it during reopen to ensure consistent behavior. Signed-off-by: Runcheng Lu

style: format code with clang-format [skip ci]

[drivers][serial/v2] fix missing break after -RT_EPERM when buf size is 0

2026-05-19T05:12:21Z

When rx_bufsz or tx_bufsz is 0, the driver returns -RT_EPERM but falls through to RT_ASSERT(rx_fifo/tx_fifo != RT_NULL). Since serial_rx/serial_tx is NULL in non-buffered mode, this triggers an assertion failure. Add break after setting ret = -RT_EPERM in the four affected cases: - RT_SERIAL_CTRL_SET_RX_TIMEOUT - RT_SERIAL_CTRL_SET_TX_TIMEOUT - RT_SERIAL_CTRL_GET_RX_TIMEOUT - RT_SERIAL_CTRL_GET_TX_TIMEOUT

fix(serial): only apply CRLF translation in STREAM mode for poll tx
