drivers: base: omit redundant interations

2017-12-18T15:47:27+00:00

When error happens, these interators return the error, no interation should be continued, so make the change for getting out of while immediately. Signed-off-by: Gimcuan Hui Signed-off-by: Greg Kroah-Hartman

driver core: Remove redundant license text

2017-12-07T17:36:44+00:00

Now that the SPDX tag is in all driver core 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.

driver core: add SPDX identifiers to all driver core files

2017-12-07T17:36:43+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 driver core 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. Cc: Johannes Berg Cc: "Luis R.

driver core: add #include to core files.

2013-08-27T17:24:15+00:00

This is needed to fix the build on sh systems. Reported-by: kbuild test robot Signed-off-by: Greg Kroah-Hartman

sysfs: add sysfs_create/remove_groups()

2013-08-21T23:02:19+00:00

These functions are being open-coded in 3 different places in the driver core, and other driver subsystems will want to start doing this as well, so move it to the sysfs core to keep it all in one place, where we know it is written properly. Signed-off-by: Greg Kroah-Hartman

driver core: bus_type: add drv_groups

2013-08-12T22:33:31+00:00

attribute groups are much more flexible than just a list of attributes, due to their support for visibility of the attributes, and binary attributes. Add drv_groups to struct bus_type which should be used instead of drv_attrs. drv_attrs will be removed from the structure soon. Signed-off-by: Greg Kroah-Hartman

driver core: don't trigger uevent after failure

2012-07-17T17:40:23+00:00

Do not send the uevent if driver_add_groups failed. Reported-by: Ming Lei Signed-off-by: Sebastian Ott Signed-off-by: Greg Kroah-Hartman

driver core: move uevent call to driver_register

2012-07-17T01:04:25+00:00

Device driver attribute groups are created after userspace is notified via an add event. Fix this by moving the kobject_uevent call to driver_register after the attribute groups are added. Signed-off-by: Sebastian Ott Signed-off-by: Greg Kroah-Hartman

Driver Core: don't oops with unregistered driver in driver_find_device()

2012-05-14T15:46:01+00:00

driver_find_device() can be called with an unregistered driver. Need to check driver_private to see if it's populated or not, especially under deferrable probe. In the case that there are 2 drivers, one depends on the other. With -EPROBE_DEFER, two drivers can use deferred probe to ensure that their relative probe order doesn't matter. If dependee driver is probed first, then the dependant's driver_find_device('dependee') succeeds. If the dependant is probed first, then the dependant's driver_find_device('dependee') should return NULL, and the dependant should get -EPROBE_DEFER. driver_find_device() needs to return NULL if it's not populated. In [PATCHv5 2/3] ARM: tegra: Add SMMU enabler in AHB: http://article.gmane.org/gmane.linux.ports.tegra/4658 "tegra_ahb_driver" may not be populated when it's called.
