[GIT PULL] Driver core fixes for 7.0-rc5

[Danilo Krummrich]

Hi Linus,

Please pull these driver-core fixes.

All commits have been in linux-next for a couple rounds; no conflicts expected.

(I will send out fixes for the remaining busses subsequently, so they can reach
you through the corresponding subsystem trees -- treewide commit [1] for
reference.)

  driver core: platform: use generic driver_override infrastructure (2026-03-17 20:30:57 +0100)

----------------------------------------------------------------
Driver core fixes for 7.0-rc5

- Generalize driver_override in the driver core, providing a common
  sysfs implementation and concurrency-safe accessors for bus
  implementations

- Do not use driver_override as IRQ name in the hwmon axi-fan driver

- Remove an unnecessary driver_override check in sh platform_early

- Migrate the platform bus to use the generic driver_override
  infrastructure, fixing a UAF condition caused by accessing the
  driver_override field without proper locking in the platform_match()
  callback
