2016-05-21T03:57:27+00:00

Pull tty and serial driver updates from Greg KH:
 "Here's the large TTY and Serial driver update for 4.7-rc1.

  A few new serial drivers are added here, and Peter has fixed a bunch
  of long-standing bugs in the tty layer and serial drivers as normal.
  Full details in the shortlog.

  All of these have been in linux-next for a while with no reported
  issues"

ISDN: eicon: replace custom hex_asc_lo() / hex_pack_byte()

2016-05-09T03:52:13+00:00

Instead of custom approach re-use generic helpers to convert byte to hex
format.

treewide: replace dev->trans_start update with helper

2016-05-04T18:16:49+00:00

Replace all trans_start updates with netif_trans_update helper.
change was done via spatch:

struct net_device *d;
@@
- d->trans_start = jiffies
+ netif_trans_update(d)

Compile tested only.

tty: Replace ASYNC_INITIALIZED bit and update atomically

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

Replace ASYNC_INITIALIZED bit in the tty_port::flags field with
TTY_PORT_INITIALIZED bit in the tty_port::iflags field. Introduce helpers
tty_port_set_initialized() and tty_port_initialized() to abstract
atomic bit ops.

Note: the transforms for test_and_set_bit() and test_and_clear_bit()
are unnecessary as the state transitions are already mutually exclusive;
the tty lock prevents concurrent open/close/hangup.

tty: Replace ASYNC_CHECK_CD and update atomically

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

Replace ASYNC_CHECK_CD bit in the tty_port::flags field with
TTY_PORT_CHECK_CD bit in the tty_port::iflags field. Introduce helpers
tty_port_set_check_carrier() and tty_port_check_carrier() to abstract
the atomic bit ops.

tty: Replace ASYNC_NORMAL_ACTIVE bit and update atomically

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

Replace ASYNC_NORMAL_ACTIVE bit in the tty_port::flags field with
TTY_PORT_ACTIVE bit in the tty_port::iflags field. Introduce helpers
tty_port_set_active() and tty_port_active() to abstract atomic bit ops.

Extract state changes from port lock sections, as this usage is
broken and confused; the state transitions are protected by the
tty lock (which mutually excludes parallel open/close/hangup),
and no user tests the active state while holding the port lock.

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().

isdn: Use ktime_t instead of 'struct timeval'

2016-03-20T20:47:13+00:00

'struct timeval' uses 32-bit representation for seconds which will
overflow in year 2038 and beyond. mISDN/clock.c needs to compute and
store elapsed time in intervals of 125 microseconds. This patch replaces
the usage of 'struct timeval' with 64-bit ktime_t which is y2038 safe.
The patch also replaces do_gettimeofday() (wall-clock time) with
ktime_get() (monotonic time) since we only care about elapsed time here.
