Hi Greg, After merging the driver-core tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: drivers/crypto/nx/nx-842.c: In function 'nx842_probe': drivers/crypto/nx/nx-842.c:1200:6: error: void value not ignored as it ought to be if (dev_set_drvdata(&viodev->dev, rcu_dereference(devdata))) { ^ Caused by commit 2c1f1ff0f0d9 ("driver core: dev_set_drvdata returns void"). Grep is better than hope :-) I have used the driver-core tree from next-20140527 for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
