[Why] Find out that when we are registering vertical interrupt0, we get DC_IRQ_SOURCE_INVALID when call dc_interrupt_to_irq_source for DCN_1_0__SRCID__OTG6_VERTICAL_INTERRUPT0_CONTROL. After analyzing, it's due to the defined value for DCN_1_0__SRCID__OTG6_VERTICAL_INTERRUPT0_CONTROL is not (DCN_1_0__SRCID__OTG5_VERTICAL_INTERRUPT0_CONTROL + 1). It's not incremental sequence. [How] Use an array to record all vertical interrupt0 SRCID. While registering interrupt, use an incremental index to visit the array to get the right SRCID to register. Also add error handling to avoid potential pointer problem.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
