/**
* blk_get_device_part_str ( ) - Get a block device and partition
*
* This calls blk_get_device_by_str ( ) to look up a device . It also looks up
* a partition and returns information about it .
*
* @ dev_part_str is in the format :
* < dev > . < hw_part > : < part > where < dev > is the device number ,
* < hw_part > is the optional hardware partition number and
* < part > is the partition number
*
* If ifname is " hostfs " then this function returns the sandbox host block
* device .
*
* If ifname is ubi , then this function returns 0 , with @ info set to a
* special UBI device .
*
* If @ dev_part_str is NULL or empty or " - " , then this function looks up
* the " bootdevice " environment variable and uses that string instead .
*
* If the partition string is empty then the first partition is used . If the
* partition string is " auto " then the first bootable partition is used .
*
* @ ifname : Interface name ( e . g . " ide " , " scsi " )
* @ dev_part_str : Device and partition string
* @ dev_desc : Returns a pointer to the block device on success
* @ info : Returns partition information
* @ allow_whole_dev : true to allow the user to select partition 0
* ( which means the whole device ) , false to require a valid
* partition number > = 1
* @ return partition number , or - 1 on error
