In function ide_devset_execute() we should use __GFP_WAIT rather than GFP_KERNEL. Also, the allocation cannot possibly fail at that point. More importantly, there is a potential memory leak in the device probing code. The infrastructure seems rather complex and I hope I haven't messed anything up by trying to fix this.

ide_lock taking is superfluous here, I removed it while merging the patch
