2011-08-16mtdinfo: don't open NULL pointer when getting region_info with `-a'Brian Norris
This "fixes" a regression found in: commit 266061ebd5d72391f0a0e831b018e8fc7fea68a1 mtdinfo: add regioninfo/eraseblock map display On certain flash (NOR flash that have eraseblock region info), `mtdinfo -a' tries to open the MTD node file, for use with the ioctl MEMGETREGIONINFO; however, we didn't supply a device node path to `mtdinfo -a', so it's using NULL, resulting in errors like: mtdinfo: error!: couldn't open MTD dev: (null) error 14 (Bad address) For now, we can just skip dumping region_info with the `-a' flag. If we find a better way to do this (e.g., export via sysfs, find device nodes via automatic routines, etc.), then we can kill the workaround and this FIXME should be removed. The regression was first reported at: http://lists.infradead.org/pipermail/linux-mtd/2011-July/037232.html The result of recent changes is that we cannot get region_info for devices via the `--all' option. We add a note in the help message warning that mtdinfo may find more info when given a device patch, e.g., /dev/mtdX.

2011-06-30mtdinfo: remove -m leftoversArtem Bityutskiy
We have removed the -m option, but did not remove args.mtdn which represents the -m parameters. Kill args.mtdn as well. Tweaked by Brian Norris. Signed-off-by: Artem Bityutskiy <dedekind1@gmail.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>
2011-06-29mtdinfo: kill -m optionBrian Norris
According to feature-removal-schedule, we shouldn't use `-m', since it relies on a specific device-naming pattern. Signed-off-by: Brian Norris <computersforpeace@gmail.com> Acked-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Artem Bityutskiy <dedekind1@gmail.com>
2011-06-29mtd-utils: switch more utils to unified versioningBrian Norris
More utilities now use the common VERSION system. For utils that printed a very simple message, we use the new common_print_version() "function."

2011-06-27rewrite build system to avoid recursionMike Frysinger
The ubi-utils/src/ subdir is tossed as it just complicates things for no real gain. The dictionary.h header is relocated to the ubi-utils/include/ since other headers in there need it. The top level clean is replaced with a `find -delete` on objects, so it might prune more than necessary, but many projects now do this sort of thing and no one complained there. A "mkdep" helper generates the actual rule, and the variables are used with "foreach" to expand these automatically. The tests subdir is updated only to reflect the ubi-utils source move. Otherwise, it is left untouched as making that non-recursive isn't really worth the effort. While we're gutting things, also through in kbuild style output while building to make things more legible.
