From: Marc-André Lureau Date: Sat, 22 Oct 2016 09:52:46 +0000 (+0300) Subject: char: remove init callback X-Git-Tag: TizenStudio_2.0_p2.3.2~9^2~14^2~5^2~117^2~25 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b4948be93e53c3b471666e51ce59303082626a2f;p=sdk%2Femulator%2Fqemu.git char: remove init callback The CharDriverState.init() callback is no longer set since commit a61ae7f88ce and thus unused. The only user, the malta FGPA display has been converted to use an event "opened" callback instead.
