Subject: [PATCH net v5 0/2] net: phy: sfp: fix mii_bus leak and revert RollBall bridge probe
Date: Sat, 27 Jun 2026 19:32:40 +0200	[thread overview]
Message-ID: <cover.1782581445.git.petr.wozniak@gmail.com> (raw)

v4 tried to fix the RollBall regression from 8fe125892f40 by deferring the
bridge probe to PHY discovery time. Maxime Chevallier and Aleksander
Bajkowski both tested that on genuine RollBall hardware and confirmed it
does not restore PHY detection (the module still is not ready when the
probe runs), and the Sashiko static review flagged the same path.

So this version drops the deferred-probe patch and instead reverts
8fe125892f40, restoring the pre-regression behaviour for genuine RollBall
modules. A proper fix for slow-initializing modules needs per-module init
timing (a longer module_t_wait / a per-module quirk) and genuine RollBall
hardware to validate; that is better owned as a follow-up by someone with
such a module.

Patch 1 is the independent mii_bus leak fix, unchanged, now carrying
Reviewed-by from Maxime and Larysa.
Patch 2 reverts 8fe125892f40.
