2016-08-21staging: slicoss: start tx queue when interface is brought upLino Sanfilippo
There is no reason to delay tx queue activation until a link is detected. So start the queue when the interface is brought up and stop it when the interface is brought down. Signed-off-by: Lino Sanfilippo <LinoSanfilippo@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2016-08-21staging: slicoss: ensure mapping of io-memory is uncachedLino Sanfilippo
Writes to registers should be done uncached for various reasons. Ensure this by replacing ioremap() with ioremap_nocache(). Signed-off-by: Lino Sanfilippo <LinoSanfilippo@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2016-08-21staging: slicoss: notifiy network stack about change in link stateLino Sanfilippo

2016-08-21staging: slicoss: handle allocation failure in slic_init_adapterLino Sanfilippo
The memory allocation in slic_init_adapter() can fail. Return an error in this case and unwind properly. Also make sure that the allocated memory is properly freed in case of an error in the calling probe() function. By doing this also replace the alloc() followed by memset to zero the memory with a zalloc() version.

2016-08-21staging: fbtft: do not allocate huge txbufMichal Suchanek

When my SPI master controller reports maximum transfer size 16M the probe of fbtft fails.

2016-08-21staging: comedi: addi_apci_3501: remove timer/counter subdevice supportH Hartley Sweeten
This driver is for a simple 4/8 channel analog output board with 2 isolated digital inputs and 2 isolated digital outputs. Support for these subdevices is provided by the driver. The boards also has a watchdog timer that can be used to reset the analog outputs. It can also be used as a general purpose 12-bit timer when the watchdog function is not necessary. The current support code for this subdevice is broken. It does not follow the comedi API and requires some out-of-tree patches in order to even work. Remove the subdevice support. If a proper register map can be located for this board we can add support back later.

2016-08-21staging: comedi: plx9080.h: rename some macros for consistencyIan Abbott
Most of the macros in "plx9080.h" that define register values are single-bits flags of the form `PLX_<REG>_<FLAG>`, or are constant, multi-bit values of the form `PLX_<REG>_<FIELD>_<VAL>`, or are non-constant, function-like macros of the form `PLX_<REG>_<FIELD>(x)`. Some of the macros for constant, multi-bit values do not currently fit the pattern, so rename them for consistency.

2016-08-21staging: comedi: plx9080.h: define PLX_<REG>_TO_<FIELD>(r) macrosIan Abbott
Various macros in "plx9080.h" take the form `PLX_<REG>_<FIELD>(x)`, where `<REG>` is a register name, `<FIELD>` is a field within the register, and `x` is a value for the field specified by the caller. The macros construct a partial register register with the specified field value placed in the appropriate bits of the register value, and other bits of the register value zeroed. Add corresponding macros of the form `PLX_<REG>_TO_<FIELD>(r)` that extract a field value from a specified register values. Remove macros of the form `PLX_<REG>_<FIELD>_SHIFT` that specified the bit position of a field within a register value as they are no longer useful.

As the enqueue() call from the Mostcore may run in parallel with the most_stop_enqueue(), the HDM may run into the inconsistent state and crash the kernel.
