[PATCH net-next v2 00/22] convert to devm_stmmac_probe_config_dt

[PATCH net-next v2 00/22] convert to devm_stmmac_probe_config_dt

[Jisheng Zhang]

Russell pointed out there's a new devm_stmmac_probe_config_dt()
helper now when reviewing my starfive gmac error handling patch[1].
After greping the code, this nice helper was introduced by Bartosz in
[2], I think it's time to convert all dwmac users to this helper and
finally complete the TODO in [2] "but once all users of the old
stmmac_pltfr_remove() are converted to the devres helper, it will be
renamed back to stmmac_pltfr_remove() and the no_dt function removed."

Link: https://lore.kernel.org/netdev/ZOtWmedBsa6wQQ6+@shell.armlinux.org.uk/ [1]
Link: https://lore.kernel.org/all/20230623100417.93592-1-brgl@bgdev.pl/  [2]

Since v1:
 - rebase on new net-next
 - add make stmmac_{probe|remove}_config_dt static as suggested by Russell.

[PATCH net-next v2 01/23] net: stmmac: dwmac-anarion: use devm_stmmac_probe_config_dt()

[Jisheng Zhang]

Simplify the driver's probe() function by using the devres
variant of stmmac_probe_config_dt().

The remove_new() callback now needs to be switched to
stmmac_pltfr_remove_no_dt().

Just a general note, IMO it's better from maintainability point of
view to use the pattern:

	ret = func();
	if (ret)
		return ret;

	return 0;

Thus should you need to add any functions call after or before the
func() method invocation with possible clean-up-on-error code the
change patch will look a bit simpler and more readable.

just "return dev_err_probe()".

Just a general note IMO it's better for maintainability to have the
clean-up-on-error block than reverting the previous changes in the if
body. Thus should you add new functions call before the block in
subject you won't need to add duplicated cleanup functions calls, but
just add new reverting method invocation to the cleanup-on-error path.

The remove_new() callback now needs to be switched to
stmmac_pltfr_remove_no_dt().

[PATCH net-next v2 19/23] net: stmmac: dwmac-sunxi: use devm_stmmac_probe_config_dt()

[Jisheng Zhang]

Simplify the driver's probe() function by using the devres
variant of stmmac_probe_config_dt().

The remove_new() callback now needs to be switched to
stmmac_pltfr_remove_no_dt().

[PATCH net-next v2 22/23] net: stmmac: rename stmmac_pltfr_remove_no_dt to stmmac_pltfr_remove

[Jisheng Zhang]

Now, all users of the old stmmac_pltfr_remove() are converted to the
devres helper, it's time to rename stmmac_pltfr_remove_no_dt() back to
stmmac_pltfr_remove() and remove the old stmmac_pltfr_remove().

[PATCH net-next v2 23/23] net: stmmac: make stmmac_{probe|remove}_config_dt static

[Jisheng Zhang]

Now there's no external users of these two functions, make them static
so that there aren't any new usages of stmmac_probe_config_dt().

To avoid forward declaration, move stmmac_remove_config_dt() location.
