UBI: fix error path in __wl_get_peb

2014-05-05T06:31:33+00:00

In case of an error (if there are not free PEB's for example), __wl_get_peb will return a negative value. In order to prevent access violation we need to test the returned value prior to using it later on.

UBI: block: Remove __initdata from ubiblock_param_ops

2014-03-21T17:37:03+00:00

You cannot mark these parameters as __initdata. Otherwise the data is gone upon module exit.

mtd: delete non-required instances of include

2014-03-11T05:42:22+00:00

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

UBI: rename block device ioctls

2014-03-05T13:49:15+00:00

Rename the UBI_IOCVOLATTBLK and UBI_IOCVOLDETBLK to UBI_IOCVOLCRBLK and UBI_IOCVOLRMBLK, because we do not use terms "attach" and "detach" for the R/O block devices on top of UBI volumes. Instead, we use terms "create" and "remove". This patch also amends the related commentaries. Signed-off-by: Artem Bityutskiy Acked-by: Ezequiel Garcia

UBI: block: Use ENOSYS as return value when CONFIG_UBIBLOCK=n

2014-03-05T13:48:35+00:00

In order to have a way of distinguishing an invalid ioctl from a not supported (but otherwise valid) ioctl, this commit changes the return value of the ioctl stubs from ENOTTY to ENOSYS. This will be useful to report more accurate error messages from userspace tools. Signed-off-by: Ezequiel Garcia Signed-off-by: Artem Bityutskiy
