Subject: drm/amd/display: Initialize stream_update with memset
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2aa632c5ffbedb2ee0e68857683466ea788f17eb;p=openwrt%2Fstaging%2Fblogic.git

drm/amd/display: Initialize stream_update with memset

The brace initialization used here generates warnings on some
compilers. For example, on GCC 4.9:

[...] In function ‘dm_determine_update_type_for_commit’:
[...] error: missing braces around initializer [-Werror=missing-braces]
   struct dc_stream_update stream_update = { 0 };
          ^

Use memset to make this more portable.

v2: Specify the compiler / diagnostic in the commit message (Paul)
