This is a note to let you know that I've just added the patch titled

usbnet: smsc95xx: Forward PHY interrupts to PHY driver to avoid polling

to the 5.15-stable tree which can be found at:

Please consider reverting upstream commit

1ce8b37241ed291af56f7a49bbdbf20c08728e88 usbnet: smsc95xx: Forward PHY interrupts to PHY driver to avoid polling")

in 5.15-stable and 5.18-stable.

I have received two independent reports (from Mark Brown and Phil Elwell) that the commit breaks link detection on LAN95xx USB Ethernet adapters in those trees.

The commit works fine in v5.19, but the backports to 5.15 and 5.18 are apparently missing prerequisites. Until we've figured out what those are, the commit should be reverted.

I had to revert 2 commits for this.

Also, 5.18 is end-of-life, no need to worry about that anymore, no one should be using it.

thanks,
