(But > strange dependency on tsc2005 at 0 is still there). Laurent, your patch looks pretty obvious, but unfortunately breaks display on Nokia N900. The patch is pretty big as is, perhaps you have version split to sdi => *sdi and then static => dynamic allocation? Thanks, Pavel commit 24aac6011f704d69b5f34514923413f85669f282 Author: Laurent Pinchart Date: Tue Feb 13 14:00:47 2018 +0200 drm: omapdrm: sdi: Allocate the sdi private data structure dynamically The sdi private data structure is currently stored as a global variable. While no platform with multiple SDI encoders currently exists nor is planned, this doesn't comply with the kernel device model and should thus be fixed. -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html -------------- next part -------------- A non-text attachment was scrubbed...
