Replace a comma between expression statements by a semicolon. This changes the semantics of the code, but given the current indentation appears to be what is intended. A simplified version of the Coccinelle semantic patch that performs this transformation is as follows: // <smpl> @r@ expression e1,e2; @@ e1 -, +; e2; // </smpl> Signed-off-by: Arushi Singhal <arushisinghal19971997@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

The IIO subsystem is redefining iio_dev->mlock to be used by the IIO core only for protecting device operating mode changes. ie. Changes between INDIO_DIRECT_MODE, INDIO_BUFFER_* modes. In this driver, mlock was being used to protect hardware state changes. Replace it with a lock in the devices global data.

The IIO subsystem is redefining iio_dev->mlock to be used by the IIO core only for protecting device operating mode changes. ie. Changes between INDIO_DIRECT_MODE, INDIO_BUFFER_* modes. In this driver, mlock was being used to protect hardware state changes. In the driver, buf_lock protects both the adis16060_spi_write() and adis16060_spi_read() functions and both are always called in pair. First write, then read. Refactor the code to have one single function adis16060_spi_write_than_read() protected by the buf_lock. This removes the need for additional locking via mlock, so this locking is removed.

Merge tag 'iio-for-4.12b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: 2nd set of new device support, features and cleanups for IIO in the 4.12 cycle A good collection of outreachy related patches in here - mostly staging driver cleanup. Also a fair number of patches added explicit OF device ID tables for i2c drivers - a precursor to dropping (eventually) the implicit probing. New Device Support * Allwinner SoC ADC. - So far covers the sun4i-a10, sun5i-a13 and sun6i-a31 general purpose ADCs, including thermal side of things. This missed the last cycle due to my incompetence, so good to get in now, particularly as various patches dependent on it are appearing. * ltc2632 - new driver supporting ltc2632-l12, ltc2632-l10, ltc2632-l8, ltc2632-h12, ltc-2632-h10, ltc-2632-h8 dacs Cleanups * Documentation - drop a broken reference to i2c/trivial-devices * ad2s1200 - drop & from function pointers for consistency. * ad2s1210 - formatting fixes. * ad7152 - octal permissions instead of symbolic. - drop & from function pointers for consistent usage. * ad7192 - drop & from function pointers for consistent usage. * ad7280 - replace core mlock usage with a local lock as mlock is intended only to protect the current device state (direct reads, or triggered and buffered) * ad7746 - drop & from function pointers for consistent usage. - replace core mlock usage with a local lock as mlock is intended only to protect the current device state (direct reads, or triggered and buffered) * ad7754 - move contents of header file into source file as not used anywhere else. * ad7759 - move contents of header file into source file as not used anywhere else. * ad7780 - drop & from function pointers for consistent usage. * ad7832 - replace core mlock usage with a local lock as mlock is intended only to protect the current device state (direct reads, or triggered and buffered) * ad9834 - replace core mlock usage with a local lock as mlock is intended only to protect the current device state (direct reads, or triggered and buffered) - drop an unnecessary goto in favour of direct return. * adis16060 - drop & from function pointers as inconsistent. * adis16201 - drop a local mutex as the adis core already protects everything necessary. - drop & from function pointers for consistent usage. * adis16203 - drop & from function pointers for consistent usage. * adis16209 - drop a local mutex as the adis core already protects everything necessary. - use an enum for scan index giving slightly nicer code. - drop & from function pointers for consistent usage. * adis16240 - drop a local mutex as the adis core already protects everything necessary. - use an enum for scan index giving slightly nicer code. - drop & from function pointers for consistent usage. * apds9960 - add OF device ID table. * bma180 - add OF device ID table. - prefer unsigned int to bare use of unsigned. * bmc150_magn - add OF device ID table. * hmp03 - add OF device ID table. * ina2xx - add OF device ID table. * itg3200 - add OF device ID table. * mag3110 - add OF device ID table. * max11100 - remove .owner field as it is set by the spi core. * max5821 - add .of_match_table set to the ID table which was present but not used. * mcp4725 - add OF device ID table. * mlx96014 - add OF device ID table. * mma7455 - add OF device ID table. * mma7660 - add OF device ID table. * mpl3115 - add OF device ID table. * mpu6050 - add OF device ID table. * pc104 - mask pc104 drivers behind a global pc104 config option. * ti-ads1015 - add OF device ID table. * tsl2563 - add OF device ID table. * us5182d - add OF device ID table.

Driver uses multiple identifier names for the same task (retval, ret, rc). It would be easier to read the code if a single task is identified with a single name. 'ret' is the most common return value identifier name found in the kernel tree, following the principle of least surprise using 'ret' is a decent choice. Rename rc -> ret Rename retval -> ret Signed-off-by: Tobin C. Harding <me@tobin.cc> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Driver uses different label forms for similar purposes. It would be more clear if single use case has uniform label. 'out' is generic and adds no meaning to label. Documentation/process/coding-style.rst: Choose label names which say what the goto does or why the goto exists. Rename labels so as to better describe what they do. If an execution path only exists for the label on an error, prefix the label with 'err_'. If a non-error execution path exist do not use prefix. Signed-off-by: Tobin C.
