Subject: [PATCH 05/12] tools perf beauty: Fix usbdevfs_ioctl table generator to handle _IOC()

From: Arnaldo Carvalho de Melo <acme@...hat.com>

In addition to _IOW() and _IOR(), to handle this case:

  #define USBDEVFS_CONNINFO_EX(len)  _IOC(_IOC_READ, 'U', 32, len)

That will happen in the next sync of this header file.
