## Overview

In the Linux kernel, the following vulnerability has been resolved:

rtc: spear: initialize IRQ state before requesting alarm IRQ

devm_request_irq() enables the interrupt before it returns, so the handler
may run while probe is still initializing the device. Initialize the MMIO
address and spinlock before requesting the alarm IRQ.

## Affected

- `Linux >= 0942a71e435f5198921e8f072540f208f0176542 < c02aa67ea34a826c2cb1aa65d77cf32fafb7eec3`
- `Linux >= 0942a71e435f5198921e8f072540f208f0176542 < e0cabda9b6f4dd276c55c40bdbb251e8507ae60e`
- `Linux >= 0942a71e435f5198921e8f072540f208f0176542 < cb6d6a7fbff0414b9eed505d17687b4b7e38fee8`
- `Linux >= 0942a71e435f5198921e8f072540f208f0176542 < 055ef5ce9f67a6a3a1363fa663007f8196cc0fb8`
