Srinivas Kandagatla 3f07c65833 nvmem: qfprom: use NVMEM_DEVID_AUTO for multiple instances ... There could be multiple qfprom devices on some SoCs. For example, on MSM8939, qfprom@58000 holds efuse bits for Core Power Reduction (CPR), and qfprom@5c000 holds bits for TSENS. Registering multiple nvmem devices with the same id results in the following failure on the second device.
