drm/i915: Extend private i915_param_named macro with description
We're always specifying description of each module param in separate macro. Let's combine description into our main macro. Started with Coccinelle, followed by minor cleanup. @match1@ declarer name MODULE_PARM_DESC; identifier n; constant c; @@ ( - MODULE_PARM_DESC(n, c); ) @fix1 depends on match1@ declarer name i915_param_named; declarer name i915_param_named_unsafe; identifier match1.n; constant match1.c; @@ ( i915_param_named(n, ... + , c ); | i915_param_named_unsafe(n, ... + , c ); ) Suggested-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Jani Nikula <jani.nikula@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20170914150805.28376-4-michal.wajdeczko@intel.com
