pcmcia: remove left-over %Z format

2017-06-07T10:07:48+00:00

commit ff5a20169b98d84ad8d7f99f27c5ebbb008204d6 upstream.

Commit 5b5e0928f742 ("lib/vsprintf.c: remove %Z support") removed some
usages of format %Z but forgot "%.2Zx".  This makes clang 4.0 reports a
-Wformat-extra-args warning because it does not know about %Z.

Replace %Z with %z.

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

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"

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: Remove ASYNC_CLOSING checks in open()/hangup() methods

2015-10-18T04:11:29+00:00

Since at least before 2.6.30, tty drivers that do not drop the tty lock
while closing cannot observe ASYNC_CLOSING set while holding the
tty lock; this includes the tty driver's open() and hangup() methods,
since the tty core calls these methods holding the tty lock.

For these drivers, waiting for ASYNC_CLOSING to clear while opening
is not required, since this condition cannot occur. Similarly, even
when the open() method drops and reacquires the tty lock after
blocking, ASYNC_CLOSING cannot be set (again, for drivers that
do not drop the tty lock while closing).

Now that tty port drivers no longer drop the tty lock while closing
(since 'tty: Remove tty_wait_until_sent_from_close()'), the same
conditions apply: waiting for ASYNC_CLOSING to clear while opening
is not required, nor is re-checking ASYNC_CLOSING after dropping and
reacquiring the tty lock while blocking (eg., in *_block_til_ready()).

Note: The ASYNC_CLOSING flag state is still maintained since several
bitrotting drivers use it for (dubious) other purposes.
