Currently fw->path values can represent one of three possible states: 1) NULL - device without the uC 2) '\0' - device with the uC but have no firmware 3) else - device with the uC and we have firmware Second case is used only to WARN at a later stage. We can WARN right away and merge cases 1 and 2. Code can be even further simplified and common (HuC/GuC logic) happening right before the fetch can be offloaded to the common function. v2: fewer temporary variables, more straightforward flow (M. Wajdeczko) v3: DRM_ERROR instead of WARN (M. Wajdeczko) v4: coding standard (J. Lahtinen) v5: non-trivial rebase v6: remove path check, we are checking fetch status (M. Wajdeczko) Cc: Anusha Srivatsa <anusha.srivatsa@intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Michal Winiarski <michal.winiarski@intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Signed-off-by: Arkadiusz Hiler <arkadiusz.hiler@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>
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.
