Can we name the function to palams_vbus_irq_handler() for better
understanding? Reserve the wakeup word for the suspend-wakeups.

Same here for better name.

This error will keep coming if the vbus is not require as workqueue get
scheduled always. I think we should remove it.

Can we change the variable names to enable_control_bus and logic
accordingly as it looks more appropriate and easy to understand?

Better to name irq1, irq2 in more logical names for easy understanding.

It need to destroy sysfs also.

It is already done above.

Better to create the workqueu when control_vbus is require.

I think it can be use palama.h only. No need to have one more header for
this.

Do we really require mailboxstat?
