[ Upstream commitce9caf2f79] We were calling enable_irq on bind, where it was already enabled previously by the IRQ helper. Additionally, dev->irq is not set correctly until after postinstall and so was always zero here, triggering a warning in 4.15. Fix both by moving the enable to the power management resume path, where we know there was a previous disable invocation during suspend.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
