Summary
In the Linux kernel, the following vulnerability has been resolved:
spi: Fix simplification of devm_spi_register_controller
This reverts commit 59ebbe40fb51 ("spi: simplify
devm_spi_register_controller").
If devm_add_action() fails in devm_add_action_or_reset(),
devm_spi_unregister() will be called, it decreases the
refcount of 'ctlr->dev' to 0, then it will cause uaf in
the drivers that calling spi_put_controller() in error path.
