* dm.c (dm_decode_dm_target_spec, dm_decode_dm_target_deps,
dm_decode_dm_name_list, dm_decode_dm_target_versions,
dm_decode_dm_target_msg, dm_decode_string, dm_known_ioctl): Fix
diagnostics about various misplaced parts of struct dm_ioctl.

decoding.
* tests/ioctl_evdev.c (main): Likewise.
* tests/ioctl_dm.c: Include <linux/ioctl.h> for _IOC_SIZE and _IOC_NR.
(main) <dummy_dm_ioctl1, dummy_dm_ioctl2, dummy_dm_arg>: New constants.
Add more checks for unknown command formatting.

b00f54e881 ioctl: do not print explicit 0x prefix and do not specify minimum width 
Specifying output width for size argument is rather misleading - it can
be up to 14 bits in size.  The use of explicit "0x" prefix is
discouraged because 0x0 looks ugly.  Usage of width specification along
with alternate form flag leads to inconsistent output for 0.
Let's use just plain %#x qualifiers instead.

* ioctl.c (ioctl_print_code): Change printf qualifiers for ioctl command
type, number and size to "%#x".
* tests/ioctl.c (main): Update expected test output.
* tests/ioctl_dm.c (main): Likewise.
* tests/ioctl_evdev.c (main): Likewise.
