Looking at drivers/mmc/core/sd.c:mmc_sd_setup_card(), returning <0 means no RO detection, and will print a warning to that effect. If no other RO-related quirks are included (i.e. such as SDHCI_QUIRK_INVERTED_WRITE_PROTECT), the value will be passed up through sdhci_get_ro and thus handled appropriately. So on second look the code as it is seems correct to me. Still, I have a 8-bit fix to incorporate, so I'll repost a v4 anyway. -Olof -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
