The hci_bcm proto is able to operate without bcm platform device linked to its uart port. In that case, firmware can be applied, but there is no power operation (no gpio/irq resources mgmt). However, the current implementation breaks this use case because of reporting a ENODEV error in the bcm setup procedure if bcm_request_irq fails (which is the case if no bcm device linked). Fix this by removing bcm_request_irq error forwarding.

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.
