By using a few more devm_ functions, we can remove the hx711_remove() function in the hx711 driver. platform_set_drvdata() is also removed since there are no more callers of platform_get_drvdata(). Signed-off-by:

David Lechner authored
This makes use of the devm_regulator_get_enable_read_voltage() helper function to simplify the code. The error return is moved closer to the function call to make it easier to follow the logic. And a few blank lines are added for readability. Signed-off-by:

Since all users were converted to the new cleanup based helper, adis_dev_lock() and adis_dev_unlock() can now be removed from the lib. Signed-off-by:

Use the new auto cleanup based locks so error paths are simpler. While at it, removed 'ret' from adis16400_write_raw() by doing return adis_write_reg_16(); instead of ret = adis_write_reg_16(); return ret; Signed-off-by:

Use the new auto cleanup based locks so error paths are simpler. While at it, reduce a bit the scope of the lock as we did not needed it protecting all the data in the switch() branch. Signed-off-by:

Use the new auto cleanup based locks so error paths are simpler. While at it, turned a sprintf() call into sysfs_emit(). Signed-off-by:

Nuno Sa authored
Add two new lock helpers that make use of the cleanup guard() and scoped_guard() macros. Thus, users won't have to worry about unlocking which is less prone to errors and allows for simpler error paths. Signed-off-by:

Nuno Sa authored
Split trigger handling for devices that have paging and need to select the correct page to get the data. Although this actually introduces more LOC, it makes the code and the locking clear. It will also make the following move to the cleanup magic cleaner. Signed-off-by:

LIS2DS12 is an accelerometer by STMicroelectronics. It is identifiable by its WhoAmI value 0x43. Its register interface is not compatible with existing parts. For example: - The full-scale values are present in register 0x20, in bits 2 and 3 (mask 0x0c). Most other supported sensors have the register address set to 0x21, 0x23, 0x24, or 0x25. There is one sensor setting though (bearing WhoAmI 0x3b) which has it's address set to 0x20, but the mask is set to 0x20, not 0x0c. - The full-scale values 2G, 4G, 8G, and 16G correspond to the register values 0x00, 0x02, 0x03, 0x01 respectively. None of the sensor settings have the value 0x01 associated with 16G. Add the compatible string without any fallback. Signed-off-by:

Add clk provider feature for the adf4350. Even though the driver was sent as an IIO driver in most cases the device is actually seen as a clock provider. This patch aims to cover actual usecases requested by users in order to completely control the output frequencies from userspace. Signed-off-by:

The ADS1119 is a precision, 16-bit, analog-to-digital converter (ADC) that features two differential or four single-ended inputs through a flexible input multiplexer (MUX), rail-to-rail input buffers, a programmable gain stage, a voltage reference, and an oscillator. Apart from normal single conversion, the driver also supports continuous conversion mode using a triggered buffer. However, in this mode only one channel can be scanned at a time.

The current error handling for calls such as devm_clk_get_enabled() in the adi-axi-dac probe() function means that, if a property such as 'clocks' (for example) is not present in the devicetree when booting a kernel with the driver enabled, the resulting error message will be vague, e.g.: |adi_axi_dac 44a00000.dac: probe with driver adi_axi_dac failed with error -2 Change the devm_clk_get_enabled(), devm_regmap_init_mmio(), and devm_iio_backend_register() checks to use dev_err_probe() with some context for easier debugging. After the change: |adi_axi_dac 44a00000.dac: error -ENOENT: failed to get clock |adi_axi_dac 44a00000.dac: probe with driver adi_axi_dac failed with error -2 Suggested-by:
