If ci_hdrc_host_init() or ci_hdrc_gadget_init() returns error and the error != -ENXIO, as Peter pointed out, "it stands for initialization for host or gadget has failed", so we'd better return failure rather continue. And before destroying the otg, i.e ci_hdrc_otg_destroy(ci), we should also check ci->roles[CI_ROLE_GADGET].

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.
