net: mdiobus: fix an OF node reference leak

2024-12-19T10:45:42Z

fwnode_find_mii_timestamper() calls of_parse_phandle_with_fixed_args() but does not decrement the refcount of the obtained OF node. Add an of_node_put() call before returning from the function. This bug was detected by an experimental static analysis tool that I am developing.

net: simplify resource acquisition + ioremap

get resource + request_mem_region + ioremap can all be done by a single function. Replace them with devm_platform_get_and_ioremap_resource or\ devm_platform_ioremap_resource where res is not used.

net: mdio-ipq4019: add missing error check

2024-11-26T10:01:39Z

If an optional resource is found but fails to remap, return on failure. Avoids any potential problems when using the iomapped resource as the assumption is that it's available.

net: mdio: Switch back to struct platform_driver::remove()

2024-10-04T23:39:57Z

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/net/mdio to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

net: mdio: thunder: switch to scoped device_for_each_child_node()

2024-10-04T16:28:26Z

There has already been an issue with the handling of early exits from device_for_each_child() in this driver, and it was solved with commit b1de5c78ebe9 ("net: mdio: thunder: Add missing fwnode_handle_put()") by adding a call to fwnode_handle_put() right after the loop. That solution is valid indeed, but if a new error path with a 'return' is added to the loop, this solution will fail. A more secure approach is using the scoped variant of the macro, which automatically decrements the refcount of the child node when it goes out of scope, removing the need for explicit calls to fwnode_handle_put().

net: mdiobus: Debug print fwnode handle instead of raw pointer

Was slightly misleading before, because printed is pointer to fwnode, not to phy device, as placement in message suggested. Include header for dev_dbg() declaration while at it.
