* watchdog: Fix the race between the release of watchdog_core_data and cdevKevin Hao2019-11-181-38/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The struct cdev is embedded in the struct watchdog_core_data. In the current code, we manage the watchdog_core_data with a kref, but the cdev is manged by a kobject. There is no any relationship between this kref and kobject. So it is possible that the watchdog_core_data is freed before the cdev is entirely released. We can easily get the following call trace with CONFIG_DEBUG_KOBJECT_RELEASE and CONFIG_DEBUG_OBJECTS_TIMERS enabled.

Fortunately, we already have a mechanism to solve this kind of issue. Please see commit 233ed09d7fda ("chardev: add helper function to register char devs with a struct device") for more detail. In this patch, we choose to embed the struct device into the watchdog_core_data, and use the API provided by the commit 233ed09d7fda to make sure that the release of watchdog_core_data and cdev are in sequence.

The current device tree does not configure the IOMUX for this pin, so it uses whathever comes configured from the bootloader. The IOMUXC_SW_PAD_CTL_PAD_EIM_BCLK register value comes as 0x8000 from the bootloader, which has PKE bit cleared, hence disabling the pull-up. Instead of relying on a previous configuration from the bootloader, configure the GPIO6_IO31 pin with pull-up enabled in order to fix this problem.

This driver depends on the guest <-> host IPC functions exported by the vboxguest driver.
