[PATCH 12/29] perf beauty ioctl: Add generator for USBDEVFS_ ioctl commands

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <a...@redhat.com>

Will be associated with fds with the right device major.

  $ tools/perf/trace/beauty/usbdevfs_ioctl.sh
  static const char *usbdevfs_ioctl_cmds[] = {
        [0] = "CONTROL",
        [10] = "SUBMITURB",
        [11] = "DISCARDURB",
        [12] = "REAPURB",
        [13] = "REAPURBNDELAY",
        [14] = "DISCSIGNAL",
        [15] = "CLAIMINTERFACE",
        [16] = "RELEASEINTERFACE",
        [17] = "CONNECTINFO",
        [18] = "IOCTL",
        [19] = "HUB_PORTINFO",
        [20] = "RESET",
        [21] = "CLEAR_HALT",
        [22] = "DISCONNECT",
        [23] = "CONNECT",
        [24] = "CLAIM_PORT",
        [25] = "RELEASE_PORT",
        [26] = "GET_CAPABILITIES",
        [27] = "DISCONNECT_CLAIM",
        [28] = "ALLOC_STREAMS",
        [29] = "FREE_STREAMS",
        [2] = "BULK",
        [30] = "DROP_PRIVILEGES",
        [31] = "GET_SPEED",
        [3] = "RESETEP",
        [4] = "SETINTERFACE",
        [5] = "SETCONFIGURATION",
        [8] = "GETDRIVER",
  };

  #if 0
  static const char *usbdevfs_ioctl_32_cmds[] = {
        [0] = "CONTROL32",
        [10] = "SUBMITURB32",
        [12] = "REAPURB32",
        [13] = "REAPURBNDELAY32",
        [14] = "DISCSIGNAL32",
        [18] = "IOCTL32",
        [2] = "BULK32",
  };
  #endif
  $

Leaving the '32' variants commented, later we can try to support those
as well, from some other hint (maybe something about the thread issuing
the ioctls) and from the _IOC_SIZE(cmd).
