Subject: drm/i915/guc: Don't store runtime GuC log level in modparam
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 50935ac767cab5494b4e15f3a95aa9e10513d82d
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
Currently we are using modparam as placeholder for GuC log level.
Stop doing this and keep runtime GuC level in intel_guc_log struct.
v2:
- rename functions intel_guc_log_level_[get|set] to
intel_guc_log_[get|set]_level (Michał Wajdeczko)
- remove GEM_BUG_ON from intel_guc_log_get_level() (Michał Wajdeczko)
