Title:
  array overrun in st7554_open

Status in sl-modem package in Ubuntu:
  In Progress

Bug description:
  In the dkms module, there is an array overrun when minor is equal to
  the size of array st7554_table in st7554_open. Fix this by making the
  comparison to be >= rather than >.

  Detected using static analysis with Coverity. I will get an upload for
  this fix sorted out in the next 48 hours.
