2016-11-23thermal: core: move trips attributes to tz->device.groupsEduardo Valentin1-38/+48
Finally, move the last thermal zone sysfs attributes to tz->device.groups: trips attributes. This requires adding a attribute_group to thermal_zone_device, creating it dynamically, and then setting all trips attributes in it. The trips attribute is then added to the tz->device.groups. As the removal of all attributes are handled by device core, the device remove calls are not needed anymore.

2016-11-23thermal: core: move passive attr to tz->device.groupsEduardo Valentin1-9/+36
This patch moves the passive attribute to tz->device.groups. Moving the passive attribute also requires a .is_visible() callback implementation for its attribute group. The logic behind the visibility of passive attribute is kept the same. We only expose the passive attribute if the thermal driver has exposed at least one passive trip point.

2016-11-23thermal: core: use dev.groups to manage always present tz attributesEduardo Valentin1-53/+34
Thermal zones attributes are all being created using device_create_file(). This has the disadvantage of making the code complicated and sometimes we may miss the cleanup of them. This patch starts to move the thermal zone sysfs attributes to the dev.groups, so Linux device core manage them for us. For now, this patch only moves those attributes are always present regardless of thermal zone condition. This change has also the advantage of cleaning up the thermal zone parameters sysfs entries that are left unclean after device registration.

This patch uses .driver_data and board_info[] to make per pci device behavior table (name and ops), instead of adding the code for each pci device in switch-case.

2016-10-27genetlink: mark families as __ro_after_initJohannes Berg1-2/+2
Now genl_register_family() is the only thing (other than the users themselves, perhaps, but I didn't find any doing that) writing to the family struct. In all families that I found, genl_register_family() is only called from __init functions (some indirectly, in which case I've add __init annotations to clarifly things), so all can actually be marked __ro_after_init. This protects the data structure from accidental corruption. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-10-27genetlink: no longer support using static family IDsJohannes Berg1-1/+0
Static family IDs have never really been used, the only use case was the workaround I introduced for those users that assumed their family ID was also their multicast group ID. Additionally, because static family IDs would never be reserved by the generic netlink code, using a relatively low ID would only work for built-in families that can be registered immediately after generic netlink is started, which is basically only the control family (apart from the workaround code, which I also had to add code for so it would reserve those IDs) Thus, anything other than GENL_ID_GENERATE is flawed and luckily not used except in the cases I mentioned. Move those workarounds into a few lines of code, and then get rid of GENL_ID_GENERATE entirely, making it more robust. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S.
