  "description": "In the Linux kernel, the following vulnerability has been resolved:  spi: oc-tiny: switch to managed controller allocation  The controller is allocated with the non-managed spi_alloc_host() while the interrupt is registered with devm_request_irq().  During removal, spi_bitbang_stop() only unregisters the controller; the subsequent spi_controller_put() then frees the controller together with its embedded driver-private devdata, which is the IRQ handler\u0027s dev_id.  The devm_request_irq() release action (free_irq()), which drains the handler, does not run until after .remove() returns.  A late or latched interrupt can therefore reach tiny_spi_irq() and dereference already-freed memory (e.g. hw-\u003Ebase).  Switch to devm_spi_alloc_host() so that the devres LIFO order releases the controller only after free_irq() has drained the handler, and drop the now-redundant spi_controller_put() from .remove().  The probe error path is simplified to direct returns.  This issue was found by an in-house static analysis tool.",
