[ Upstream commit5df816e7f4] When initializing the device (procedure init_one), the driver calls mlx5_pci_init to perform pci initialization. As part of this initialization, mlx5_pci_init creates a debugfs directory. If this creation fails, init_one aborts, returning failure to the caller (which is the probe method caller). The main reason for such a failure to occur is if the debugfs directory already exists. This can happen if the last time mlx5_pci_close was called, debugfs_remove (silently) failed due to the debugfs directory not being empty. Guarantee that such a debugfs_remove failure will not occur by instead calling debugfs_remove_recursive in procedure mlx5_pci_close.

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.
