Subject: initialize width/height fields in drmModeCrtc
X-Git-Tag: android-x86-4.4-r1~188
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=e81acf51013d5d4245417c46ee6b4055c26f1a91;p=android-x86%2Fexternal-libdrm.git

initialize width/height fields in drmModeCrtc

If we have valid timings, we can at least set width/height to
*something*, which is I think at least less confusing than always
seeing width/height of zero.  At least modeprint and modetest
seem to expect width/height to mean something.
