Hi Greg, here are two patches for the onewire subsystem.
The first allows to have DS28E04 eproms on the bus (which have a peculiar address-crc quirk when using the address strapping pins). The second fixes a long-standing bug with hanging of a DS2490 USB interface when some chips (that lock the bus mutex during add) are discovered, e.g. https://github.com/raspberrypi/linux/issues/3491. I initially sent to Evgeniy (cc), but he asked to resend to you and Cc lkml. Chris
