In the Linux kernel, the following vulnerability has been resolved:gpio: Restrict usage of GPIO chip irq members before initializationGPIO chip irq members are exposed before they could be completelyinitialized and this leads to race conditions.One such issue was observed for the gc->irq.domain variable whichwas accessed through the I2C interface in gpiochip_to_irq() beforeit could be initialized by gpiochip_add_irqchip().

CVE-2022-49072

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

gpio: Restrict usage of GPIO chip irq members before initialization

GPIO chip irq members are exposed before they could be completely
initialized and this leads to race conditions.

One such issue was observed for the gc->irq.domain variable which
was accessed through the I2C interface in gpiochip_to_irq() before
it could be initialized by gpiochip_add_irqchip(). This resulted in
Kernel NULL pointer dereference.

Following are the logs for reference :-

kernel: Call Trace:
kernel: gpiod_to_irq+0x53/0x70
kernel: acpi_dev_gpio_irq_get_by+0x113/0x1f0
kernel: i2c_acpi_get_irq+0xc0/0xd0
kernel: i2c_device_probe+0x28a/0x2a0
kernel: really_probe+0xf2/0x460
kernel: RIP: 0010:gpiochip_to_irq+0x47/0xc0

To avoid such scenarios, restrict usage of GPIO chip irq members before
they are completely initialized.
