This patch removes typedef from the struct linux_wlan_t and renames it to the wilc. In addition, all of linux_wlan_t is replaced with struct wilc and memory allocation style is changed with preferred form as well like the following: p = kmalloc(sizeof(*p), ...) where "struct wilc" is used Signed-off-by:

Merge tag 'iio-for-4.4b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Second set of new drivers, functionality and cleanups for IIO in the 4.4 cycle. Core stuff * adjust resistance documentation to allow for output devices. New device support: * bmc150 - split the i2c driver up into a core and i2c_regmap part including regmap conversion. - add spi support. * mcp4531 digitial potentiometer driver. * Measurement Specialties set of drivers with a core library module providing common functionality. Note that the htu21 has a driver in hwmon, but the view from that side was that, given the range of devices the same silicon turns up in are not all typical hwmon material, that driver would be deprecated in favour of this new support. - ms8607 temperature, pressure and humidty sensor - ms5637 temperature and pressure sensor - htu21 temperature and humidity sensor - tsys02d temperature sensor - tsys01 temperature sensor Cleanups * tree wide. - squish cases where irq 0 is still considered valid. * apds9960 - sparse endian warning cleanups by making endianness explicit. * ad5504 - leave group naming to the core. * ad7746 - cleanup comment style. - drop an unnecessary bit of dev_info - add some appropriate uses of the BIT macro. * ad799x - leave group naming to the core. * hdc100x - introduced this cycle,. - fix a wrong offset value. * lidar - add missing MODULE_DEVICE_TABLE for dt. * max1363 - leave sysfs group naming to the core. * m62332 got the Harmut treatment and as ever he found a 'few' bits the rest of us had missed! - Share scale and offset attributes across channels. - Shutdown the device on driver remove - Use ARRAY_SIZE rather than a hard coded count for channels. - Return more directly in the write_raw callback dropping a local variable along the way. - a few style issues - move to reading the regulator voltage for each use allowing for dynamic regulators. This is a common feature across drivers so we might end up with more fixes throughout the tree for this. * mlx96014 - introduced this cycle. - fixed up a spot of error handling. * vz89x - introduced this cycle. - work around a hardware quirk.

In a recent change, we made a bool into a tristate in: "drivers/staging: make android tegra_ion.c properly tristate", since it was self evident that was the original intention. However on the final link phase we'll see an allmodconfig fail with: ERROR: "ion_device_add_heap" [drivers/staging/android/ion/tegra/tegra_ion.ko] undefined! ERROR: "ion_heap_create" [drivers/staging/android/ion/tegra/tegra_ion.ko] undefined! ERROR: "ion_device_create" [drivers/staging/android/ion/tegra/tegra_ion.ko] undefined! ERROR: "ion_heap_destroy" [drivers/staging/android/ion/tegra/tegra_ion.ko] undefined! ERROR: "ion_device_destroy" [drivers/staging/android/ion/tegra/tegra_ion.ko] undefined! Export the above using the non GPL specific export, since that is what the rest of the ion code base does.

Some drivers use member screen_base of struct fb_info to store non- __iomem pointers, creating the need for ugly __force typecasts to avoid sparse warnings. This adds an alternate pointer without the __iomem qualifyer for this use. Signed-off-by:

If the "read" file operation handler, `comedi_read()` is passed 0 for the amount to read, some error conditions are currently skipped and the function just returns 0. Change it to check those error conditions and return an error value if appropriate. The trickiest case is the check for when the previously set up asynchronous command has terminated with an error. In that case, `-EPIPE` is returned (as it is for a read of non-zero length) and the subdevice gets marked as non-busy. A zero-length read that returns 0 has no other effects, in particular, it does not cause the subdevice to be marked as non-busy, and the return value does not indicate an "end-of-file" condition.

In order to perform a "read" file operation, an asynchronous COMEDI command in the "read" direction needs to have been set up by the current file object on the COMEDI "read" subdevice associated with the file object. If there is a "read" subdevice, but a command has not been set up by the file object (or is has been set-up in the wrong direction), `comedi_read()` currently returns one of two error values `-EINVAL` or `-EACCES`. `-EACCES` is returned if the command was set up by a different subdevice, or somewhat randomly, if a COMEDI "instruction" is currently being processed. `-EINVAL` is returned in other cases. Simplify it by returning `-EINVAL` for all these cases. Signed-off-by:

The "read" file operation handler, `comedi_read()` returns an error for pretty much any condition that prevents a "read" going ahead. One of the conditions that prevents a "read" going ahead is that no asynchronous command has been set up, but that currently results in a return value of 0 (unless COMEDI instructions are being processed or an asynchronous command has been set up by a different file object). Change it to return `-EINVAL` in this case. Signed-off-by:

`comedi_read()` copies data from the acquisition data buffer, which is cyclic, to the user buffer using a single call to `copy_to_user()`. It currently avoids having to deal with wraparound of the cyclic buffer by limiting the amount it copies (and the amount returned to the user). Change it to deal with the wraparound using two calls to `copy_to_user()` if necessary. Signed-off-by:

At one point in `comedi_read()`, the variable `n` gets assigned to the minimum of the parameter `nbytes` and the amount of readable buffer space `m`. The way that is done currently is unsafe in the unlikely case that `nbytes` exceeds `UINT_MAX`, so fix it. Signed-off-by:

In `comedi_read()`, the `n` and `m` variables are of type `int`. Change them to `unsigned int` as they are used to measure a positive number of bytes. The `count` variable is also of type `int` and holds the returned number of bytes. Change it to type `ssize_t` to match the function's return type. Signed-off-by:

`comedi_read()` is the handler for the "read" file operation for COMEDI devices. It mostly runs without using the main mutex of the COMEDI device, but uses the `attach_lock` rwsemaphore to protect against the COMEDI device becoming "detached". A file object can read data resulting from a COMEDI asynchonous command if it initiated the command. The COMEDI subdevice is marked as busy when the command is started. At some point, the "read" handler detects that the command has terminated and all available data has been read and so marks the subdevice as non-busy. In order to mark the subdevice as non-busy, the "read" handler needs to release the `attach_lock` rwsemaphore and `acquire the main `mutex`. There is a vulnerable point between the two, so it checks that the device is still attached after acquiring the mutex. However, it does not currently check that the conditions for becoming non-busy still hold. Add some more checks that the subdevice is still busy with a command initiated by the same file object, that command is in the correct direction (in case the subdevice supports both "read" and "write"), that command has terminated, and has no data available to be read.
