Staging: lustre: Iterate list using list_for_each_entry
Code using doubly linked list is iterated generally using list_empty and
list_entry functions, but it can be better written using list_for_each_entry
macro.
This patch replaces the while loop containing list_empty and list_entry with
list_for_each_entry and list_for_each_entry_safe. list_for_each_entry is a
macro which is used to iterate over a list of given type. So while loop used to
iterate over a list can be replaced with list_for_each_entry macro. However, if
list_del is used in the loop, then list_for_each_entry_safe is a better choice.
This transformation is done by using the following coccinelle script.

Staging: iio: Change data type to u16 to avoid unnecessary typecast
In the adis16220_read16bit() function we earlier used a s16 value 'val'
which is used by the adis_read_reg_16 function to read data and takes a
u16 value as a parameter.
So, this patch changes the data type of 'val' from s16 to u16. It is safe
to remove the extra sign extension, since the user of the function uses it
to read a 10 unsigned value which will lead to the same result in both cases.
Further this patch removes the unnecessary typecast for the simplification of
code. In addition to this, initialization of 'val' to 0 is also dropped. This is
due to the fact that not initializing helps the compiler provide useful warnings
if the code gets changed to return an otherwise uninitialized result.

TTY: fix tty_wait_until_sent maximum timeout
Currently tty_wait_until_sent may take up to twice as long as the
requested timeout while waiting for driver and hardware buffers to
drain.
Fix this by taking the remaining number of jiffies after waiting for
driver buffers to drain into account so that the timeout actually
becomes a maximum timeout as it is documented to be.
Note that this specifically implies tighter timings when closing a port
as a consequence of actually honouring the port closing-wait setting
for drivers relying on tty_wait_until_sent_from_close (e.g. via
tty_port_close_start).

TTY: fix tty_wait_until_sent on 64-bit machines
Fix overflow bug in tty_wait_until_sent on 64-bit machines, where an
infinite timeout (0) would be passed to the underlying tty-driver's
wait_until_sent-operation as a negative timeout (-1), causing it to
return immediately.
This manifests itself for example as tcdrain() returning immediately,
drivers not honouring the drain flags when setting terminal attributes,
or even dropped data on close as a requested infinite closing-wait
timeout would be ignored.
The first symptom was reported by Asier LLANO who noted that tcdrain()
returned prematurely when using the ftdi_sio usb-serial driver.
Fix this by passing 0 rather than MAX_SCHEDULE_TIMEOUT (LONG_MAX) to the
underlying tty driver.
Note that the serial-core wait_until_sent-implementation is not affected
by this bug due to a lucky chance (comparison to an unsigned maximum
timeout), and neither is the cyclades one that had an explicit check for
negative timeouts, but all other tty drivers appear to be affected.

TTY: bfin_jtag_comm: remove incorrect wait_until_sent operation
Remove incorrect and redundant wait_until_sent operation, which waits
for the driver buffer rather than any hardware buffers to drain,
something which is already taken care of by the tty layer (and
chars_in_buffer).

net: irda: fix wait_until_sent poll timeout
In case an infinite timeout (0) is requested, the irda wait_until_sent
implementation would use a zero poll timeout rather than the default
200ms.
Note that wait_until_sent is currently never called with a 0-timeout
argument due to a bug in tty_wait_until_sent.

UART drivers use the UPIO_* definitions, but the uapi header defines

thus the userspace values are definitive.

console: Fix console name size mismatch
commit
6ae9200f2cab7 ("enlarge console.name") increased the storage
for the console name to 16 bytes, but not the corresponding
struct console_cmdline::name storage. Console names longer than
8 bytes cause read beyond end-of-string and failure to match
console; I'm not sure if there are other unexpected consequences.

tty: fix up atime/mtime mess, take four
This problem was taken care of three times already in

atime/mtime on read/write),

*
b0b885657b6c8ef63a46bc9299b2a7715d19acde (tty: fix up atime/mtime
mess, take three)
But it still misses one point. As John Paul correctly points out, we
do not care about setting date. If somebody ever changes wall
time backwards (by mistake for example), tty timestamps are never
updated until the original wall time passes.
So check the absolute difference of times and if it large than "8
seconds or so", always update the time. That means we will update
immediatelly when changing time. Ergo, CAP_SYS_TIME can foul the
check, but it was always that way.
Thanks John for serving me this so nicely debugged.

serial: 8250_dw: Fix get_mctrl behaviour
Fixed behaviour of get_mctrl() serial driver function as documented in:
https://www.kernel.org/doc/Documentation/serial/driver
Added device-tree properties 'dcd-override', 'dsr-override',
'cts-override', and 'ri-override' specific to the Synopsis 8250
DesignWare UART driver. Allows one to force Data Carrier Detect,
Clear To Send, and Data Set Ready signals to permanently be reported as
active. The Ring indicator can be forced to be reported as inactive.
It is possible that if modem control signalling is enabled on a port
that doesn't have these pins (e.g. - a simple two wire Tx/Rx port), the
driver can hang indefinitely waiting for the state to change. The new
DT properties allow the driver to ignore the state of these pins on
serial ports that don't support them, as recommended in the kernel
documentation.
