synchronizing accesses with nand_base

I've inherited some code that implements the chip interface for our board, and also implements *user_prot* interfaces for OTP access. We ran into some problems that seem to be due to the fact that the OTP accesses can collide with regular filesystem accesses. I noticed that the nand_base.c code uses a nand_get_device/nand_release_device for synchronization, but those routines appear to be private to that file. What is the proper way to add device-specific routines for OTP access while following proper synchronization procedures.

Thanks for any help.
