      8250_pci: Add support for the Digi/IBM PCIe 2-port Adapter · aa273ae5
      由 Scott Kilau 提交于 
      Add support to the 8250 PCI serial driver for the Digi/IBM PCIe 2-port Async EIA-232 Adapter.

Oxford Semiconductor produces a 2/4/8 port UART (OXPCIe952/OXPCIe954/OXPCIe958) chip
called the Tornado, that can be used to create a very simple serial board product.
The kernel sources currently have just 2 vendors using this chip, which is Oxford and Mainpipe.
This new Digi/IBM serial product now uses it as well.

Rather than create a long running comment of vendors using the chip, the one changed comment
in the patch below now just lists "For Oxford Semiconductor Tornado based devices" to be a
more generic comment for all vendors that end up using the Oxford Tornado chip.

      drivers/serial/ucc_uart.c: Add of_node_put to avoid memory leak · 48a10cdf
      由 Julia Lawall 提交于 
      Add a call to of_node_put in the error handling code following a call to
of_find_compatible_node or of_find_node_by_type.

This patch also substantially reorganizes the error handling code in the
function, to that it is possible first to jump to code that frees qe_port
and then to jump to code that also puts np.

The semantic match that finds this problem is as follows:
