* There are several ways to specify UBI volumes when mounting UBIFS:
* o ubiX_Y - UBI device number X, volume Y;
* o ubiY - UBI device number 0, volume Y;
* The primary method of mounting UBIFS is by specifying the UBI volume
* character device node path. However, UBIFS may also be mounted withoug any
* character device node using one of the following methods:
*
* o ubiX_Y - mount UBI device number X, volume Y;
* o ubiY - mount UBI device number 0, volume Y;
* o ubiX:NAME - mount UBI device X, volume with name NAME;
* o ubi:NAME - mount UBI device 0, volume with name NAME.
*
* Alternative '!' separator may be used instead of ':' (because some shells
* like busybox may interpret ':' as an NFS host name separator). This function
* returns ubi volume object in case of success and a negative error code in
* case of failure.
* returns UBI volume description object in case of success and a negative
* error code in case of failure.
