Drop static on a local variable, when the variable is initialized before use, on every possible execution path through the function. The static has no benefit, and dropping it reduces the code size. The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @bad exists@ position p; identifier x; type T; @@ static T x@p; ... x = <+...x...+> @@ identifier x; expression e; type T; position p != bad.p; @@ -static T x@p; ... when != x when strict ?x = e; // </smpl> The change in code size is indicates by the following output from the size command. before: text data bss dec hex filename 3879 512 8 4399 112f drivers/iio/accel/hid-sensor-accel-3d.o after: text data bss dec hex filename 3863 512 0 4375 1117 drivers/iio/accel/hid-sensor-accel-3d.o Signed-off-by:

MAX31856 is register equivalent to the MAX31855 but suppports J, N, R, S, T, E and B type thermocouples in addition to K-type. Data conversion for the various types happens transparently to the driver via probe type detection, and a LUT on the sensor. Signed-off-by:

Meson GX SoCs however use some magic bits to prevent simultaneous (= conflicting, because only consumer should use the FIFO buffer with the ADC results) usage by the Linux kernel and the bootloader (the BL30 bootloader uses the SAR ADC to read the CPU temperature). This patch changes guards all BL30 functionality so it is skipped on SoCs which don't have it. Since the hardware itself doesn't know whether BL30 is available the internal meson_sar_adc_data is extended so this information can be provided per of_device_id.data inside the driver. Additionally the clocks "adc_clk" and "adc_sel" are not provided by the clock-controller itself. "adc_sel" is not available at all. "adc_clk" is provided by the SAR ADC IP block itself on Meson8b (and earlier). This is already supported by the meson_saradc driver. Finally this introduces new of_device_ids for the Meson8 and Meson8b SoCs so the driver can be wired up in the corresponding DT. Signed-off-by:

The Amlogic Meson SAR ADC driver can be used on Meson8 and Meson8b (probably on earlier SoC generations as well, but I don't have any hardware available for testing that). Add a separate compatible for Meson8 and Meson8b because it does not need any of the BL30 magic (unlike the GX SoCs). Signed-off-by:

These are only passed as of_device_id.data and never modified. Thus we can mark them as static const, just like the of_device_id instances where they are used. Signed-off-by:

Geomagnetic orientation(AM) sensor is one kind of orientation 6dof sensor. It gives the device rotation in respect to the earth center and the magnetic north. The sensor is implemented through use of an accelerometer and magnetometer do not use gyroscope. It is a standard HID sensor. More information can be found in: http://www.usb.org/developers/hidpage/HUTRR59_-_Usages_for_Wearables.pdf Geomagnetic orientation(AM) sensor and dev rotation sensor have same channel and share channel usage id. So the most of the code for relative orientation sensor can be reused. Signed-off-by:

isl29030 is basically the same chip. The only difference is the chip's first pin. For isl29028 its named ADDR0 and can be used to change the chip's i2c address. For isl29030 on the other hand that pin is named Ials and is an analog current output proportional to ALS/IR. This change is irrelevant for the Linux driver. This has been tested on Motorola Droid 4.

Build tested using: $ make -C <kernelsrcdir> tools/iio $ make -C <kernelsrcdir>/tools iio $ make -C <kernelsrcdir>/tools/iio This follows a strategy similar to that used by tools/hv, tools/net and tools/leds among others.

Without this patch, the driver fails to register the sensors when the user removes and re-loads the driver. 1.

Brian Masney authored
The sysfs attribute in_proximity_sampling_frequency_available currently shows the values 1 3 5 10 13 20 83 100. These values are supposed to correspond to the sleep values 800 400 200 100 75 50 12.5 0 (all in ms). When passing in a sampling frequency of 3, it actually uses a sleep time of 200ms instead of the expected 400ms value. This patch changes the value shown by this sysfs attribute to use fixed-point numbers so that the correct sampling frequency is shown to the user. This patch also changes the code that updates the proximity sampling frequency to only allow values that are shown in the _available sysfs attribute. The original code showed the value 83 that corresponds to the sleep time 12 ms. The data sheet actually lists 12.5 ms as the sleep time, so the proximity frequency was updated to 80. Signed-off-by:

Laura Abbott authored
ion_handle was introduced as an abstraction to represent a reference to a buffer via an ion_client. As frameworks outside of Ion evolved, the dmabuf emerged as the preferred standard for use in the kernel. This has made the ion_handle an unnecessary abstraction and prone to race conditions. ion_client is also now only used internally. We have enough mechanisms for race conditions and leaks already so just drop ion_handle and ion_client. This also includes ripping out most of the debugfs infrastructure since much of that was tied to clients and handles. The debugfs infrastructure was prone to give confusing data (orphaned allocations) so it can be replaced with something better if people actually want it. Signed-off-by:

The current model of Ion heap registration is based on the outdated model of board files. The replacement for board files (devicetree) isn't a good replacement for what Ion wants to do. In actuality, Ion wants to show what memory is available in the system for something else to figure out what to use. Switch to a model where Ion creates its device unconditionally and heaps are registed as available regions. Currently, only system and CMA heaps are converted over to the new model. Carveout and chunk heaps can be converted over when someone wants to figure out how. Signed-off-by:

Several of the Ion ioctls were designed in such a way that they necessitate compat ioctls. We're breaking a bunch of other ABIs and cleaning stuff up anyway so let's follow the ioctl guidelines and clean things up while everyone is busy converting things over anyway. As part of this, also remove the useless alignment field from the allocation structure. Signed-off-by:

Laura Abbott authored
When CMA was first introduced, its primary use was for DMA allocation and the only way to get CMA memory was to call dma_alloc_coherent. This put Ion in an awkward position since there was no device structure readily available and setting one up messed up the coherency model. These days, CMA can be allocated directly from the APIs. Switch to using this model to avoid needing a dummy device. This also mitigates some of the caching problems (e.g. dma_alloc_coherent only returning uncached memory). Signed-off-by:
