Subject: perf ui: Add ui_progress__finish()
X-Git-Tag: upstream/snapshot3+hdmi~6128^2~3^2~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a5580f3ecb295a514f9522daf0ef7158f73ec2d6;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

perf ui: Add ui_progress__finish()

Sometimes we need to know when the progress bar should disappear.

Checking curr >= total wasn't enough since there're cases not met that
condition for the last call.

So add a new ->finish callback to identify this explicitly.  Currently
only GTK frontend needs it.
