Subject: drm/amd/display: Add dm_logger_append_va API
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d6f068a53b5a7d719e7c66554356a2af6da9cda7;p=openwrt%2Fstaging%2Fblogic.git

drm/amd/display: Add dm_logger_append_va API

Same as dm_logger_append, except it takes a va_list instead of a
variable number of arguments. dm_logger_append is now a minimal wrapper
around dm_logger_append_va.
