siox: Make remove callback return void

2020-12-10T15:17:15Z

The driver core ignores the return value of the remove callback, so don't give siox drivers the chance to provide a value. All siox drivers only allocate devm-managed resources in .probe, so there is no .remove callback to fix.

siox: Use bus_type functions for probe, remove and shutdown

2020-12-10T15:17:15Z

The eventual goal is to get rid of the callbacks in struct device_driver. Tested-by: Thorsten Scherer Acked-by: Thorsten Scherer Signed-off-by: Uwe Kleine-König Link: https://lore.kernel.org/r/20201125093106.240643-2-u.kleine-koenig@pengutronix.de Signed-off-by: Greg Kroah-Hartman

siox: Use the correct style for SPDX License Identifier

2020-01-14T20:46:53Z

This patch corrects the SPDX License Identifier style in header file related to Eckelmann SIOX driver. For C header files Documentation/process/license-rules.rst mandates C-like comments (opposed to C source files where C++ style should be used).

treewide: Add SPDX license identifier - Makefile/Kconfig

2019-05-21T08:50:46Z

Add SPDX license identifiers to all Make/Kconfig files which: - Have no license information of any form These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman

headers: separate linux/mod_devicetable.h from linux/platform_device.h

2018-07-07T15:52:26Z

At over 4000 #includes, is the 9th most #included header file in the Linux kernel. It does not need , so drop that header and explicitly add to source files that need it. 4146 #include After this patch, there are 225 files that use , for a reduction of around 3900 times that does not have to be read & parsed. 225 #include This patch was build-tested on 20 different arch-es. It also makes these drivers SubmitChecklist#1 compliant.

siox: don't create a thread without starting it

2018-07-07T15:38:57Z

When a siox master device is registered a kthread is created that is only started when triggered by userspace. So this thread might be in TASK_UNINTERRUPTIBLE state for long and trigger a warning [ 241.130465] INFO: task siox-0:626 blocked for more than 120 seconds. with the respective debug settings enabled. It might be right to put an unstarted thread to TASK_IDLE (in kernel/kthread.c:kthread()) instead, but independant of this discussion it is cleaner for siox_master_register() to start the thread immediately. The effect is that it enters its own waiting state and then stays in state TASK_IDLE which doesn't trigger the above warning. As siox_poll_thread() uses some variables of the device the initialisation of these is moved before thread creation.

siox: treat type errors as status errors

2018-07-07T15:38:57Z

The type bits are part of the per-device status word. So it's natural to consider an error in the type bits as a status error instead of only resulting in an unsynced state. Signed-off-by: Uwe Kleine-König Acked-by: Gavin Schenk Signed-off-by: Greg Kroah-Hartman

siox: fix possible buffer overflow in device_add_store

Width 20 given in format string is larger than destination buffer 'type[20]', use %19s to prevent overflowing it.
