2022-11-10stmmac: dwmac-loongson: fix missing of_node_put() while module exitingYang Yingliang1-5/+14
The node returned by of_get_child_by_name() with refcount decremented, of_node_put() needs be called when finish using it. So add it in the error path in loongson_dwmac_probe() and in loongson_dwmac_remove().

2022-11-03stmmac: dwmac-loongson: fix invalid mdio_nodeLiu Peibao1-5/+2
In current code "plat->mdio_node" is always NULL, the mdio support is lost as there is no "mdio_bus_data". The original driver could work as the "mdio" variable is never set to false, which is described in commit <b0e03950dd71> ("stmmac: dwmac-loongson: fix uninitialized variable ......"). And after this commit merged, the "mdio" variable is always false, causing the mdio supoort logic lost.

2022-04-04stmmac: dwmac-loongson: change loongson_dwmac_driver from global to staticTom Rix1-1/+1
Smatch reports this issue dwmac-loongson.c:208:19: warning: symbol 'loongson_dwmac_driver' was not declared. Should it be static? loongson_dwmac_driver is only used in dwmac-loongson.c. File scope variables used only in one file should be static. Change loongson_dwmac_driver's storage-class-specifier from global to static.
