Subject: [PATCH 00/12] xen: add common function for reading optional value

There are multiple instances of code reading an optional unsigned
parameter from Xenstore via xenbus_scanf(). Instead of repeating the
same code over and over add a service function doing the job and
replace the call of xenbus_scanf() with the call of the new function
where appropriate.

Juergen Gross (12):
  xen: introduce xenbus_read_unsigned()
  xen: make use of xenbus_read_unsigned() in xen-blkback
  xen: make use of xenbus_read_unsigned() in xen-blkfront
  xen: make use of xenbus_read_unsigned() in xen-tpmfront
  xen: make use of xenbus_read_unsigned() in xen-kbdfront
  xen: make use of xenbus_read_unsigned() in xen-netback
  xen: make use of xenbus_read_unsigned() in xen-netfront
  xen: make use of xenbus_read_unsigned() in xen-pcifront
  xen: make use of xenbus_read_unsigned() in xen-scsifront
  xen: make use of xenbus_read_unsigned() in xen-fbfront
  xen: make use of xenbus_read_unsigned() in xen-pciback
  xen: make use of xenbus_read_unsigned() in xenbus
