[ Upstream commit b5bfc21af5cb3d53f9cee0ef82eaa43762a90f81 ] When we probe a SFP module, we expect to be able to call the upstream device's module_insert() function so that the upstream link can be configured. However, when the upstream device is delayed, we currently may end up probing the module before the upstream device is available, and lose the module_insert() call. Avoid this by holding off probing the module until the SFP bus is properly connected to both the SFP socket driver and the upstream driver.

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.
