Subject: drm/i915/guc: work around gcc-4.4.4 union initializer issue
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=401d0ae326c92185f1727b0f12834197536265ae;p=linux.git

drm/i915/guc: work around gcc-4.4.4 union initializer issue

gcc-4.4.4 has problems with initalizers of anon unions.

drivers/gpu/drm/i915/intel_guc_log.c: In function 'guc_log_control':
drivers/gpu/drm/i915/intel_guc_log.c:64: error: unknown field 'logging_enabled' specified in initializer

Work around this.
