4Subject: [PATCH] Revert "Return correct error number in ubi_get_vol_info1"
5
6This reverts commit dede98ffb706676309488d7cc660f569548d5930.
7
8The original commit tried to fix a descrepancy between the implementation
9and the documentation by making the implementation comply.
10
11When making the change, it was overlooked, that ubinfo and ubirename were
12written against the implementation instead of the behaviour specified by
13the documentation. So were further internal functions like
14ubi_get_vol_info1_nm which further breaks ubirmvol.
15
16A report with an outline of a resulting problem can be read on
17the mailing list:

21From the report:
22
23steps to reproduce: have mtd-utils 2.0.1 or 2.0.2
24
250. make a bunch of ubi volumes in sequential order
26
27ubimkvol /dev/ubi0 -s 64KiB -N test1
28ubimkvol /dev/ubi0 -s 64KiB -N test2
29ubimkvol /dev/ubi0 -s 64KiB -N test3
30ubimkvol /dev/ubi0 -s 64KiB -N test4
31..
32
331. delete the test1 volume, making a hole in the volume table
34
35ubirmvol /dev/ubi0 -N test1
36
372. try an affected tool (i.e. "ubirmvol /dev/ubi0 -N test4" )
