Make MTD core tolerate SPI controllers without OTP support and report an error from MTD core if OTP initialization fails early.
These changes address the issue that occurs when an OTP capable SPI NOR device is initialized with the Intel SPI controller. The limited supported opcode set of the SPI controller leads to failure in the OTP initialization, which in turn fails the probe for the MTD device. By allowing the MTD core to tolerate unsupported OTP, the rest of the MTD functionality remains intact even if OTP initialization is unsupported.
Aapo Vienamo (2): mtd: core: Report error if first mtd_otp_size() call fails in mtd_otp_nvmem_add() mtd: core: Don't fail mtd_device_parse_register() if OTP is unsupported
