I remember this commit 6eb1c9496b81680f2cd2e0eda06c531317e2e28d clk: probe common clock drivers earlier going in recently, but it's rather dubious it could cause such trouble. Anyway, I'd try to add some debug prints to samsung_i2s_probe() to see what's the issue with the CPU DAI registration. > But I thought the patches had merits on its own since probe deferral > can make a driver probe many times and the error logs were noisy.

In general I wouldn't be disabling those err logs unless proper EPROBE_DEFER handling is added on related error paths and we can differentiate between probe deferral and real unrecoverable errors and can disable logging only for EPROBE_DEFER cases. >> As far as the error log is concerned, I would just not print anything >> in snow_probe() when register_card() returns EPROBE_DEFER. >> > > I believe it may be useful to know that a driver's probe is deferring > due a missing dependency but have no strong opinion and can remove the > message. I'd rather rely on core code to inform about missing resources when registering components. Otherwise booting unnecessarily takes more time when there is more probe deferring logs printed on the console. -- Thanks, Sylwester _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
