Subject: [PATCH v3 0/2] drm/i915: Avoid full proxy f_ops debug attributes

This patch series proposes to replace a combination of DEFINE_SIMPLE_ATTRIBUTE() +
debugfs_create_file() by a combination of DEFINE_DEBUGFS_ATTRIBUTE() +
debugfs_create_file_unsafe(). The change reduced overhead in terms of managing
the full proxy f_ops at runtime. The patches 1 & 2 covers for the DRRS and FBC
f_ops debugfs attributes respectively.

Following coccicheck make command helped identify this change:

make coccicheck M=drivers/gpu/drm/i915/ MODE=patch COCCI=./scripts/coccinelle/api/debugfs/debugfs_simple_attr.cocci

Changes in v3:
   Patch 1/2: fix checkpatch function parameter alignment complaint
   Patch 2/2: None

Changes in v2:
   - Individual patches clubbed in patch set
   - Update patch log message to include coccicheck make command


Deepak R Varma (2):
  drm/i915/display: Avoid full proxy f_ops for DRRS debug attributes
  drm/i915/fbc: Avoid full proxy f_ops for FBC debug attributes
