Subject[PATCH 0/2] mtd: core: Handle unsupported OTP operations
Date
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
