On controllers that implement\nSET_FEATURES via multiple low-level PIO commands, these can race with\nconcurrent UBI/UBIFS background erase/write operations that hold the\ndevice lock, resulting in cmd_pending conflicts on the NAND controller.\n\nAdd nand_get_device()/nand_release_device() around the lock/unlock\noperations to serialize them against all other NAND controller access.",
