This patch adds functionality to validate and convert either a device name or 'ser' memmber of synth into dev_t. Subsequent patch in this set will call it to convert user-specified device into device number. For device name, this patch does some basic sanity checks on the string passed in. It currently supports ttyS*, ttyUSB* and, for selected synths, lp*. The patch also introduces a string member variable named 'dev_name' to struct spk_synth. 'dev_name' represents the device name - ttyUSB0 etc - which needs conversion to dev_t. Signed-off-by:

The function converts strings like ttyS0 and ttyUSB0 to dev_t like (4, 64) and (188, 0). It does this by scanning tty_drivers list for corresponding device name and index. If the driver is not registered, this function returns -ENODEV. It also acquires tty_mutex. Signed-off-by:

Merge tag 'iio-for-4.13b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Second set of IIO new device support, features and cleanups for the 4.13 cycle. A few reverts here. One was a general failure to notice a device was already supported by another driver. The second is due to a review comment pointing out that the original patch was a bad idea and would break existing systems. Reverts * bma180 - Revert addition of support for the BMA250E it is already supported by the bmc150-accel and better supported at that. Oops. * hi8435 - The fix for cleanup of the reset gpio stuff isn't a good way to go. It breaks systems where an inverting level convertor is used. The right fix is to make the original devicetree correct - even if it involves patching the devicetree in kernel. New Device Support * stm32-adc - STM32H7 support and bindings. Features * core - add a hardware triggered operating mode for systems in which the actual trigger is never seen by the kernel. This is typically only used when a device 'can' use other triggers, but if a particular magic one is enabled the interrupt is effectively handled in hardware and we never see it. * st-lsm6dsx - support active low interrupts. * stm32-adc - Make the core adc clock optional as not all hardware supported requires it. - Make the bus clock optional in the per instance driver as it may be shared by all instances of the ADC and is handled by the core. - Rework to have a data structure representing the device type specific elements. * stm32-trigger (and counter) - Use the INDIO_HARDWARE_TRIGGERED_MODE where appropriate. - Add an attribute to configure device modes for quadrature counting etc. Clean ups and minor fixes * IIO core. - use __sysfs_match_string() helper rather than open coding the same. * ad7791 - use sysfs_match_string() helper rather than open coding the same. * aspeed-adc - handle return value of clk_prepare_enable * cpcap - Fix default register values and ensure the battery thermistor is enabled correctly. - Fix the reported die temperature where we can - docs are lacking. - Remove the hung interrupt quirk as no longer happens due to fix in the mfd driver. * hi8435 - Remove &s from hi8435_info definition as unneeded and inconsistent. * hid-sensor-trgger - Add kconfig depends on IIO_BUFFER (fixes patch in previous series) * ina2xx - Make the use of iio_info_mask* elements consistent for all channels. This doesn't have any visible effect, but acts as clear documentation of which channels various resulting attributes apply to. * lpc32xx - handle the return value of clk_prepare_enable. * meson-saradc - NULL instead of 0 for pointer. * mma9551 - use NULL for GPIO connection ID to aid implementation fo ACPI support. Here the connection ID doesn't actually tell us anything and it is much easier to deal with the driver if it's not there. * mpu6050 - Fix lock issues through use of a local mux. - Replace sprintf with scnprintf as appropriate. - Check whoami against all known values. This allows for a small number of boards where we are really fishing for the part not being present at all. It is unfortunately common to have undescribed changes to use newer chips. We paper over this but just emitting a warning for those cases as long as we know about. * mxs-lradc - Fix some non static warnings. * rcar-adc - Part of making the naming for this part consistent across the kernel. * st_accel - drop some spi_device_id entries for variants with no SPI support * st_magn - drop some spi_device_id entries for variants with no SPI support. * sx9500 - Use devm_gpiod_get instead of indexed value with an index of 0 on all occasions. * twl4030 - Drop unused twl4030_get_madc_conversion as callers removed now throughout kernel. - Unexport twl4030_madc_conversion() as no used only within this driver. - Drop twl4030_madc_user_params as not used now. - Drop twl4030_madc_request.func_cb as not used now. - Fold the twl4030-madc.h header into the driver as no longer used anywhere else in the kernel. * xilinx - Handle the return value of clk_prepare_enable

This patch adds definition of tty_open_by_driver when CONFIG_TTY is not defined. This was supposed to have been included in commit 12e84c71 ("tty: export tty_open_by_driver"). The patch follows convention for other such functions and returns NULL. Signed-off-by:

synths[] array caches currently loaded synths. synth_add checks synths[] before adding a new one. It however ignores the result of do_synth_init. So when do_synth_init fails, the failed synth is still cached. Since, as a result module loading fails too, synth_remove - which is responsible for removing the cached synth - is never called. Next time the failing synth is added again it succeeds because synth_add finds it cached inside synths[]. This patch fixes this by caching a synth only after do_synth_init succeeds. Signed-off-by:

The original ccree driver was registering a useless setkey method even for non-MAC hash transformations. Somewhere around v4.9 a check was added that failed hash operations if a setkey method was registered but was not called, so during the initial upstream port code was added to only register the setkey method for MAC type hash transform. Unfortunately, the ccree driver also registers non-hash based MAC transforms and the code had a logic error that stopped it registering a setkey callback even for those, thus rendering them useless. This commit fixes the logic mistake, thus correctly registering a setkey method only for MAC transformations, leaving it out for non-MAC ones, whether they are hash based on not. Fixes: 50cfbbb7 ("staging: ccree: add ahash support"). Signed-off-by:

le16_to_cpu() accepts argument of type __le16 and cpu_to_le16() returns an argument of type __le16. This patch fixes: (a) the type of the variable that end's up getting return from cpu_to_le16(). (b) the member types of struct hfa384x_host_scan_request_data, struct hfa384x_bytestr32 and struct hfa384x_hscan_result_sub.

The header field in struct pd_message is declared as an __le16 type. The data in the message is supposed to be little endian. This means we don't have to go and shift the individual bytes into position when we're filling the buffer, we can just copy the contents right away. As an added benefit we don't get fishy results on big endian systems anymore. Signed-off-by:
