[PATCH 37/46] mtd: nandsim: Turn parts[] into a integer

From: Richard Weinberger The parts array denotes how many erase blocks each partition has. Therefore a plain integer can also do it. If someone shows me a NAND with more than 2^32 erase blocks we can turn it back into a long. ;) Signed-off-by: Richard Weinberger --- drivers/mtd/nand/nandsim.c

[PATCH 46/46] mtd/nandsim: Add ioctl for info

Add a ioctl() call for nandsim information. This information includes, nand id, backend type and path to the file if the file backend is used Signed-off-by: Daniel Walter --- drivers/mtd/nand/nandsim.c | 65 + include/uapi/mtd/nandsim-user.h | 11

[PATCH 02/46] mtd: nand: TODO Propagate mtd_device_unregister() return value in tear down

From: Richard Weinberger Provide a __nand_release() function for drivers which can deal with a failing nand release operation. Most drivers should be safe since they rely on module refcounting. To catch outliers implement a nand_release() with a WARN_ON(). Signed-off-by: Richard
