2299 Routine Description:\r
2300 Convert text to the binary representation of a device path.\r
2301\r
2302 Arguments:\r
2303 TextDevicePath - TextDevicePath points to the text representation of a device\r
2304 path. Conversion starts with the first character and continues\r
2305 until the first non-device node character.\r
2306\r
2307 Returns:\r
2308 A pointer - Pointer to the allocated device path.\r
2309 NULL - If TextDeviceNode is NULL or there was insufficient memory.\r
