Merge tag 'staging-4.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

2016-05-21T05:20:48+00:00

Pull staging and IIO driver updates from Greg KH:
 "Here's the big staging and iio driver update for 4.7-rc1.

  I think we almost broke even with this release, only adding a few more
  lines than we removed, which isn't bad overall given that there's a
  bunch of new iio drivers added.

  The Lustre developers seem to have woken up from their sleep and have
  been doing a great job in cleaning up the code and pruning unused or
  old cruft, the filesystem is almost readable :)

  Other than that, just a lot of basic coding style cleanups in the
  churn.  All have been in linux-next for a while with no reported
  issues"

staging: dgnc: Need to check for NULL of ch

2016-05-09T12:10:03+00:00

dgnc_board(brd) was already checked for NULL before calling
neo_parse_isr(). And also port doesn't need to check.

staging: dgnc: clean up the dgnc_get_modem_info()

2016-05-09T12:10:03+00:00

the "ch" in dgnc_get_modem_info() was already checked before calling
this function and also if "ch" is not NULL, dgnc_get_mstat() returns
valid value so it doesn't need to check an error.

staging: dgnc: Fix a NULL pointer dereference

2016-05-04T05:57:14+00:00

The error handling for print_drive after calling tty_alloc_driver()
was needed. But there was error handling but too late for this.
Error handling code moved after tty_alloc_driver() call.

tty: Replace TTY_IO_ERROR bit tests with tty_io_error()

2016-04-30T16:26:55+00:00

Abstract TTY_IO_ERROR status test treewide with tty_io_error().
NB: tty->flags uses atomic bit ops; replace non-atomic bit test
with test_bit().

staging: dgnc: use tty_alloc_driver instead of kcalloc

2016-04-30T00:46:00+00:00

The tty_alloc_driver() can allocate memory for ttys and termios.
And also allocated memory will be released easily with
put_tty_driver() call.

error code with ENOMEM
