staging: most: remove legacy folders

2017-11-28T12:36:21Z

This patch removes the legacy folders of the modules. It is needed to clean up the driver's source tree. Signed-off-by: Christian Gromm Signed-off-by: Greg Kroah-Hartman

staging: most: cdev: rename module

2017-11-27T08:20:33Z

This patch renames the folder of the cdev module. This is needed to clear the directory layout. Signed-off-by: Christian Gromm Signed-off-by: Greg Kroah-Hartman

staging: most: move core files

2017-11-27T08:20:33Z

This patch moves the core files to the root dir of the driver. This is needed to clean up the directory layout. Signed-off-by: Christian Gromm Signed-off-by: Greg Kroah-Hartman

staging: most: Remove redundant license text

2017-11-27T08:20:33Z

Now that the SPDX tag is in all most driver files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

staging: most: add SPDX identifiers to all most driver files

2017-11-27T08:20:33Z

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/staging/most files files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

staging: most: destroy cdev when channel gets disconnected

2017-04-08T10:41:39Z

When a channel is being removed while an application holds the corresponding character device, this device is going to be destroyed only after the application closes the file descriptor and releases character device. In case the channel appears again before the application closes the file descriptor it holds, the channel cannot be linked. This patch changes the described behavior and destroys the character device at the time the channel get disconnected from the AIM.

staging: most: aim-cdev: make syscall write accept buffers of arbitrary size

2016-09-23T17:00:44Z

This patch allows to call the write() function for synchronous and isochronous channels with buffers of any size. The AIM simply waits for data to fill up the MOST buffer object according to the network interface controller specification for streaming channels, before it submits the buffer to the HDM. The new behavior is backward compatible to the old applications, since all known applications needed to fill the buffer completely anyway.

staging: most: make function most_submit_mbo return void

2016-09-22T09:54:46Z

Function most_submit_mbo() causes an exception only if either the pointer mbo or mbo->context equals NULL. From the underlying architecture's point of view both cases must _not_ come true and would happen only, if something has tampered with the pointers. This would render runtime code unable to recover anyway. So, instead trying to hide that things are already critically out of control we're better off with a WARN_ON() assertion. This patch replaces the return type of the function most_submit_mbo() with 'void' and adds a WARN_ONCE() assertion. Additionally, code calling the function is adapted accordingly.

staging: most: aim-cdev: destroy ida struct in case of exception

2016-08-22T20:41:00Z

This patch is needed to clean up the initialized ida structure in case the function exits with an exception. Signed-off-by: Christian Gromm Signed-off-by: Greg Kroah-Hartman

staging: most: aim-cdev: report error returned by alloc_chrdev_region

2016-08-21T14:50:38Z

This patch forwards the error code returned by function alloc_chrdev_region(). It is needed to stop the module from hiding the actual cause of failure. Signed-off-by: Christian Gromm Signed-off-by: Greg Kroah-Hartman
