I'll have to mark spi_nor_spansion_clear_sr_bp() and spi_nor_unlock_global_block_protection() definitions as __maybe_unused.
drivers/mtd/spi-nor/spi-nor.c:1729:12: warning: ‘spi_nor_unlock_global_block_protection’ defined but not used [-Wunused-function] static int spi_nor_unlock_global_block_protection(struct spi_nor *nor) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/mtd/spi-nor/spi-nor.c:1687:12: warning: ‘spi_nor_spansion_clear_sr_bp’ defined but not used [-Wunused-function] static int spi_nor_spansion_clear_sr_bp(struct spi_nor *nor) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
