@Aakash - The warning shows up because the device’s kobject is being initialized twice.

The first initialization occurs on platform_device_alloc() and again with platform_device_register().

Essentially, it's trying to reinitialize an already set-up object.

Even though the warning appears, it doesn’t affect the functionality. The module loads and unloads fine since the kernel handles this extra initialization without issues.

Hope that helps clarify things!
