Subject: [PATCH] drm/msm/dp: Add a missing semi-colon
Date: Sat, 6 Feb 2021 20:18:58 -0800 [thread overview]
Message-ID: <20210207041858.3317171-1-swboyd@chromium.org> (raw)
A missing semicolon here causes my external display to stop working.
Indeed, missing the semicolon on the return statement leads to
dp_panel_update_tu_timings() not existing because the compiler thinks
it's part of the return statement of a void function, so it must not be
important.
$ ./scripts/bloat-o-meter before.o after.o
add/remove: 1/1 grow/shrink: 0/1 up/down: 7400/-7540 (-140)
Function old new delta
dp_panel_update_tu_timings - 7400 +7400
_dp_ctrl_calc_tu.constprop 18024 17900 -124
dp_panel_update_tu_timings.constprop 7416 - -7416
Total: Before=54440, After=54300, chg -0.26%
Add a semicolon so this function works like it used to.
