Subject: [PATCH 2/8] stmmac: move error path at the end of
|
|
stmmac_probe_config_dt()
|
|
|
|
We will want to do additional clean-up on certain errors. Therefore,
|
|
this change moves the error path at the end of the function for better
|
|
code readability.
|
|
|
|
This patch doesn't change anything functionally.
