Linux kernel source tree

When removing the tidss driver, there is a warning reported by kernel about an unhandled interrupt for mhdp driver. [ 43.238895] irq 31: nobody cared (try booting with the "irqpoll" option) ... [snipped backtrace] [ 43.330735] handlers: [ 43.333020] [<000000005367c4f9>] irq_default_primary_handler threaded [<000000007e02b601>] cdns_mhdp_irq_handler [cdns_mhdp8546] [ 43.344607] Disabling IRQ #31 This happens because as part of cdns_mhdp_bridge_hpd_disable, driver tries to disable the interrupts. While disabling the SW_EVENT interrupts, it accidentally enables the MBOX interrupts, which are not handled by the driver. Fix this with a read-modify-write to update only required bits. Use the enable / disable function as required in other places.

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.
