changes v2:
- split the patch set.
This patch set is part of the preparatory work for migrating the lan78xx
USB Ethernet driver to the PHYlink framework. During extensive testing,
I observed that resetting the USB adapter can lead to various read/write
errors. While the errors themselves are acceptable, they generate
excessive log messages, resulting in significant log spam. This set
improves error handling to reduce logging noise by addressing errors
directly and returning early when necessary.
Key highlights of this series include:
- Enhanced error handling to reduce log spam while preserving the
original error values, avoiding unnecessary overwrites.
- Improved error reporting using the `%pe` specifier for better clarity
in log messages.
- Removal of redundant and problematic PHY fixups for LAN8835 and
KSZ9031, with detailed explanations in the respective patches.
- Cleanup of code structure, including unified `goto` labels for better
readability and maintainability, even in simple editors.
