[PATCH] MPBL0010 driver sysfs permissions wide open
The MPBL0010 Telco clock driver (drivers/char/tlclk.c) uses 0222 (anyone can write) permissions on its writable sysfs entries. Alter the permissions to 0220 (owner and group can write). The use case for this driver is to configure the fail over behavior of the clock hardware. That should be done by the more privileged users.
