Seunghui Lee 886da99e8f mmc: core: Set read only for SD cards with permanent write protect bit ... commit 917a5336f2c27928be270226ab374ed0cbf3805d upstream. Some of SD cards sets permanent write protection bit in their CSD register, due to lifespan or internal problem. To avoid unnecessary I/O write operations, let's parse the bits in the CSD during initialization and mark the card as read only for this case.
