staging: dgrp: Remove casting the return value which is a void pointer

2013-09-17T14:47:43+00:00

Casting the return value which is a void pointer is redundant.
The conversion from void pointer to any other pointer type is
guaranteed by the C programming language.

Merge tag 'tty-3.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

2013-09-03T18:38:36+00:00

Pull tty/serial driver patches from Greg KH:
 "Here's the big tty/serial driver pull request for 3.12-rc1.

  Lots of n_tty reworks to resolve some very long-standing issues,
  removing the 3-4 different locks that were taken for every character.
  This code has been beaten on for a long time in linux-next with no
  reported regressions.

  Other than that, a range of serial and tty driver updates and
  revisions.  Full details in the shortlog"

tty: Ensure single-threaded flip buffer consumer with mutex

2013-07-23T23:47:09+00:00

The buffer work may race with parallel tty_buffer_flush. Use a
mutex to guarantee exclusive modify access to the head flip
buffer.

Remove the unneeded spin lock.

drivers: avoid format string in dev_set_name

2013-07-03T23:07:41+00:00

Calling dev_set_name with a single paramter causes it to be handled as a
format string.  Many callers are passing potentially dynamic string
content, so use "%s" in those cases to avoid any potential accidents,
including wrappers like device_create*() and bdi_register().

drivers: staging: dgrp: using time_is_before_jiffies() instead of open coding 'jiffies'

2013-06-09T05:20:59+00:00

Need use the proper jiffy comparison macros/functions instead of open
coding 'jiffies'.

The original 'comparation' is always true.

staging: for dgrp, let nd_ps_desc always NUL terminated string within MAX_DESC_LEN length

2013-05-13T22:08:16+00:00

Use strlcpy instead of strncpy to let nd_ps_desc always NUL terminated.

Change nd_ps_desc in nd_struct struct to MAX_DESC_LEN to avoid the
confusion (the related length checking also need be changed to
MAX_DESC_LEN - 1).

Pull VFS updates from Al Viro,

Misc cleanups all over the place, mainly wrt /proc interfaces (switch
create_proc_entry to proc_create(), get rid of the deprecated
create_proc_read_entry() in favor of using proc_create_data() and
seq_file etc).

7kloc removed.
