[PATCH] drm/i915: Add Sphinx-compatible references to struct fields

From: Jonathan NeuschÃfer
Date: Thu Oct 03 2019 - 13:29:02 EST


This fixes the following kernel-doc warnings and makes the corrsponding fields
show up in the generated HTML:

./drivers/gpu/drm/i915/i915_drv.h:1143: warning: Incorrect use of kernel-doc format: * State of the OA buffer.
./drivers/gpu/drm/i915/i915_drv.h:1154: warning: Incorrect use of kernel-doc format: * Locks reads and writes to all head/tail state
./drivers/gpu/drm/i915/i915_drv.h:1176: warning: Incorrect use of kernel-doc format: * One 'aging' tail pointer and one 'aged' tail pointer ready to
./drivers/gpu/drm/i915/i915_drv.h:1188: warning: Incorrect use of kernel-doc format: * Index for the aged tail ready to read() data up to.
./drivers/gpu/drm/i915/i915_drv.h:1193: warning: Incorrect use of kernel-doc format: * A monotonic timestamp for when the current aging tail pointer
./drivers/gpu/drm/i915/i915_drv.h:1199: warning: Incorrect use of kernel-doc format: * Although we can always read back the head pointer register,
