Subject: Bug 1859786 - Fix lock annotation warning in Mozilla-specific edit on
|
|
top of video_capture_impl.cc. r=webrtc-reviewers,mjf
|
|
|
|
The annotations were added in M116:
|
|
https://hg.mozilla.org/mozilla-central/rev/9cd372df013948ad822ae936752d725d77474fb5
|
|
|
|
Note that this was never unsafe, since _dataCallbacks is only written on the
|
|
same thread that we are patching here. This patch however, adds helpful static
|
|
analysis.
