2012-08-27spi/topcliff-pch: Fix device remove functionGuenter Roeck
The call sequence spi_alloc_master/spi_register_master/spi_unregister_master is complete; it reduces the device reference count to zero, which results in device memory being freed. An extra call to spi_master_put is unnecessary and results in an access to free memory. Drop it. Also, the device subsystem resets device driver data to NULL after the call to the remove function returns, so there is no need to do it here.

2012-08-27spi/tegra: Fix device remove functionGuenter Roeck
The call to spi_unregister_master() in the device remove function frees device memory, and with it any device local data. However, device local data is still accessed after the call to spi_unregister_master(). Acquire a reference to the SPI master device and release it after cleanup is complete to solve the problem.

2012-08-27spi/stmp: Fix device remove functionGuenter Roeck
The call sequence spi_alloc_master/spi_register_master/spi_unregister_master is complete; it reduces the device reference count to zero, which results in device memory being freed. The remove function accesses the freed memory after the call to spi_unregister_master(), _and_ it calls spi_master_put on the freed memory. Acquire a reference to the SPI master device and release it after cleanup is complete (with the existing spi_master_put) to solve the problem. Also, the device subsystem ensures that the remove function is only called once, and resets device driver data to NULL. Remove the respective check and drop the unnecessaary call to platform_set_drvdata(). Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-08-23spi/sc18is602: Return -EINVAL for probe failures due to I2C function mismatchGuenter Roeck
If the I2C bus master driver does not support the required functionality, the driver returns -ENODEV. This causes a silent probe failure without error message. Since the device has to be explicitly instantiated, and the user should know the correct bus, this event really reflects an error condition. Replace error return value with -EINVAL to trigger an error message showing that the probe function failed.

The call sequence spi_alloc_master/spi_register_master/spi_unregister_master is complete; it reduces the device reference count to zero, which results in device memory being freed. An extra call to spi_master_put is unnecessary and results in an access to free memory. At the same time, since the call to spi_unregister_master results in device memory being freed, it must no longer be accessed afterwards.

2012-08-16autofs4 - fix get_next_positive_subdir()Ian Kent
Following a report of a crash during an automount expire I found that the locking in fs/autofs4/expire.c:get_next_positive_subdir() was wrong. Not only is the locking wrong but the function is more complex than it needs to be. The function is meant to calculate (and dget) the next entry in the list of directories contained in the root of an autofs mount point (an autofs indirect mount to be precise). The main problem was that the d_lock of the owner of the list was not being taken when walking the list, which lead to list corruption under load. The only other lock that needs to be taken is against the next dentry candidate so it can be checked for usability.

On a 2-node machine with 256GB of ram we get 512 lines of console output, which is just too much.

2012-08-14drm/i915: reorder edp disabling to fix ivb MacBook AirDaniel Vetter
eDP is tons of fun. It turns out that at least the new MacBook Air 5,1 model absolutely doesn't like the new force vdd dance we've introduced in commit 6cb49835da0426f69a2931bc2a0a8156344b0e41 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Sun May 20 17:14:50 2012 +0200 drm/i915: enable vdd when switching off the eDP panel But that patch also tried to fix some neat edp sequence issue with the force_vdd timings. Closer inspection reveals that we've raised force_vdd only to do the aux channel communication dp_sink_dpms. If we move the edp_panel_off below that, we don't need any force_vdd for the disable sequence, which makes the Air happy. Unfortunately the reporter of the original bug that the above commit fixed is travelling, so we can't test whether this regresses things. But my theory is that since we don't check for any power-off -> force_vdd-on delays in edp_panel_vdd_on, this was the actual root-cause of this failure. With that force_vdd dance completely eliminated, I'm hopeful the original bug stays fixed, too. For reference the old bug, which hopefully doesn't get broken by this: https://bugzilla.kernel.org/show_bug.cgi?id=43163 In any case, regression fixers win over plain bugfixes, so this needs to go in asap. v2: The crucial pieces seems to be to clear the force_vdd flag uncoditionally, too, in edp_panel_off. Looks like this is left behind by the firmware somehow. v3: The Apple firmware seems to switch off the panel on it's own, hence we still need to keep force_vdd on, but properly clear it when switching the panel off.

2012-08-13drm/i915: ensure i2c adapter is all set before adding itJani Nikula
i2c_add_adapter() may do i2c transfers on the bus to detect supported devices. Therefore the adapter needs to be all set before adding it. This was not the case for the bit-banging fallback, resulting in an oops if the device detection GMBUS transfers timed out. Fix the issue by calling i2c_add_adapter() only after intel_gpio_setup().

2012-08-13drm/radeon/kms: add MSAA texture support for r600-evergreenMarek Olšák
Most of the checking seems to be in place already. As you can see, log2(number of samples) resides in LAST_LEVEL. This is required for MSAA support (namely for depth-stencil resolve and blitting between MSAA resources).
