2011-10-19staging:iio:dac:ad5686: Check for negative valuesLars-Peter Clausen
Currently it is possible to write negative values to the ad5686's raw attribute. This will cause undefined behaviour, so reject negative values. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Acked-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2011-10-19staging:iio:dac:ad5791: Allow asymmetrical reference voltagesLars-Peter Clausen
The ad5791 currently assumes that the negative and positive supply have the same absolute value, which is not necessarily true. This patch introduces a offset attribute which will contain the negative supply voltage scaled according to the iio spec. The raw attribute now accepts values in the range of 0 to max instead of -max/2 to max/2. While we are at it also fix the vref span calculation. Since both positive and negative reference voltages are specificed as absolute values we need to add them and not subtract them to get the reference voltage span.

2011-10-19usb/isp1760: Allow to optionally trigger low-level chip reset via GPIOLIB.Joachim Foerster
Properly triggering the reset wire is necessary with the ISP1761 used on Terasic DE4 Altera-FPGA boards using a NIOS2 processor, for example. This is an optional implementation for the OF binding only. The other bindings just pass an invalid GPIO to the isp1760_register() routine. Example, usage in DTS: gpios = <&pio_isp1761rst_0 0 1>; to point to a GPIO controller from within the ISP1761 node: GPIO 0, active low.

2011-10-19TTY: serial_core: Fix crash if DCD drop during suspendDoug Anderson
This crash was showing up 100% of the time on Tegra CPUs when an agetty was running on the serial port and the console was not running on the serial port. The reason the Tegra saw it so reliably is that the Tegra CPU internally ties DTR to DCD/DSR. That means when we dropped DTR during suspend we would get always get an immediate DCD drop. The specific order of operations that were running: * uart_suspend_port() would be called to put the uart in suspend mode * we'd drop DTR (ops->set_mctrl(uport, 0)). * the DTR drop would be looped back in the CPU to be a DCD drop. * the DCD drop would look to the serial driver as a hangup * the hangup would call uart_shutdown() * ... suspend / resume happens ... * uart_resume_port() would be called and run the code in the (port->flags & ASYNC_SUSPENDED) block, which would startup the port (and enable tx again). * Since the UART would be available for tx, we'd immediately get an interrupt, eventually calling transmit_chars() * The transmit_chars() function would crash. The first crash would be a dereference of a NULL tty member, but since the port has been shutdown that was just a symptom. I have proposed a patch that would fix the Tegra CPUs here (see https://lkml.org/lkml/2011/10/11/444 - tty/serial: Prevent drop of DCD on suspend for Tegra UARTs). However, even with that fix it is still possible for systems that have an externally visible DCD line to see a crash if the DCD drops at just the right time during suspend: thus this patch is still useful.

2011-10-19phylib: Modify Vitesse RGMII skew settingsAndy Fleming
The Vitesse driver was using the RGMII_ID interface type to determine if skew was necessary. However, we want to move away from using that interface type, as it's really a property of the board's PHY connection. However, some boards depend on it, so we want to support it, while allowing new boards to use the more flexible "fixups" approach. To do this, we extract the code which adds skew into its own function, and call that function when RGMII_ID has been selected. Another side-effect of this change is that if your PHY has skew set already, it doesn't clear it. This way, the fixup code can modify the register without config_init then clearing it.

2011-10-19bonding: use local function pointer of bond->recv_probe in bond_handle_frameMitsuo Hayasaka
The bond->recv_probe is called in bond_handle_frame() when a packet is received, but bond_close() sets it to NULL. So, a panic occurs when both functions work in parallel. Why this happen: After null pointer check of bond->recv_probe, an sk_buff is duplicated and bond->recv_probe is called in bond_handle_frame. So, a panic occurs when bond_close() is called between the check and call of bond->recv_probe. Patch: This patch uses a local function pointer of bond->recv_probe in bond_handle_frame(). So, it can avoid the null pointer dereference.
