treewide: Use DEVICE_ATTR_RO

2018-01-09T15:34:34+00:00

Convert DEVICE_ATTR uses to DEVICE_ATTR_RO where possible. Done with perl script: $ git grep -w --name-only DEVICE_ATTR | \ xargs perl -i -e 'local $/; while (<>) { s/\bDEVICE_ATTR\s*$\s*(\w+)\s*,\s*\(?(?:\s*S_IRUGO\s*|\s*0444\s*)$?\s*,\s*\1_show\s*,\s*NULL\s*\)/DEVICE_ATTR_RO(\1)/g; print;}' Signed-off-by: Joe Perches Acked-by: Rafael J.

s390: drivers: Remove redundant license text

2017-11-24T13:28:47+00:00

Now that the SPDX tag is in all drivers/s390/ 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.

s390: cio: add SPDX identifiers to the remaining files

2017-11-24T13:28:41+00:00

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/s390/cio/ 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.

s390/cio: css initialization cleanup

2017-01-16T06:27:52+00:00

Simplify error handling during css initialization by moving the error handling code to setup_css (which now cleans up after itself). Also remove the odd special cleanup handling of the pseudo_subchannel. Signed-off-by: Sebastian Ott Reviewed-by: Cornelia Huck Reviewed-by: Peter Oberparleiter Signed-off-by: Martin Schwidefsky

Note that this change does not affect the channel subsystem id as used in the user-visible naming of subchannels and friends.

s390/cio: clarify cssid usage

2017-01-16T06:27:52+00:00

Currently the cssid in various structures is used as the id of the respective channel subsystem. Sometimes however we call the index in the channel_subsystems array cssid. In some places the id is even used as the index. Provide a new define MAX_CSS_IDX and use it where appropriate. In addition to that provide a dummy function to find a channel subsystem by its id and a macro to iterate over the channel subsystems.
