There is a potential probe issue in how we trigger the hw initialisation. Although we use 1s timer to delay hw initialisation, there is still a potential that sas_register_ha() is not be finished before we start the PHY init from hw->hw_init(). To avoid this issue, initialise the hw after sas_register_ha() in the same probe context. Note: it is not necessary to use 1s timer now (modified v2 hw only).

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.
