This series contains minor fixes needed to better support running an rmtfs daemon from an unprivileged process: - Enable uevents on the child character device by adding a struct class to the parent. I needed these so that I could change the ownership of /dev/qcom_rmtfs_mem1, and drove myself crazy trying to understand why my udev rules never fired. - Enable access to phys_addr and size sysfs attributes. The daemon needs to read these, and they don't really contain anything sensitive, so expose them.
I still need CAP_NET_ADMIN to be able to bind to the right qrtr port, but at least with these changes I can run as a different user, and drop all other privileges.
Changes in v3: - Removed spurious whitespace changes (Brian, Bjorn)
Changes in v2: - Moved class registration/deregistration into init/exit routines (Brian)
