Subject: drm/i915: have *_debugfs_init() functions return void.
Git-commit: f06b2052f74d7b42ff8cbfe1ac0b78be7668c37d
Patch-mainline: v5.8-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Since commit 987d65d01356 (drm: debugfs: make
drm_debugfs_create_files() never fail), drm_debugfs_create_files() never
fails and should return void. Therefore, remove its use as the
return value of debugfs_init() functions and have the functions return
void.
v2: convert intel_display_debugfs_register() stub to return void too.
