driver_find_device: Unify the match function with class_find_device()

2019-06-24T03:22:31Z

The driver_find_device() accepts a match function pointer to filter the devices for lookup, similar to bus/class_find_device(). However, there is a minor difference in the prototype for the match parameter for driver_find_device() with the now unified version accepted by {bus/class}_find_device(), where it doesn't accept a "const" qualifier for the data argument. This prevents us from reusing the generic match functions for driver_find_device(). For this reason, change the prototype of the driver_find_device() to make the "match" parameter in line with {bus/class}_find_device() and adjust its callers to use the const qualifier. Also, we could now promote the "data" parameter to const as we pass it down as a const parameter to the match functions.

driver-core: return EINVAL error instead of BUG_ON()

2018-05-25T16:18:45Z

I triggerd the BUG_ON() in driver_register() when booting a domU Xen domain. Since there was no contextual information logged, I needed to attach kgdb to determine the culprit (the wmi-bmof driver in my case). The BUG_ON() was added in commit f48f3febb2cb ("driver-core: do not register a driver with bus_type not registered"). Instead of running into a BUG_ON() we print an error message identifying the, likely faulty, driver but continue booting. Signed-off-by: Florian Schmaus Signed-off-by: Greg Kroah-Hartman

drivers: base: omit redundant interations

2017-12-18T15:47:27Z

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

2017-12-07T17:36:44Z

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

2017-12-07T17:36:43Z

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.

sysfs: add sysfs_create/remove_groups()

2013-08-21T23:02:19Z

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

2013-08-12T22:33:31Z

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
