Merge branch 'uverbs_dev_cleanups' into rdma.git for-next
For dependencies, branch based on rdma.git 'for-rc' of https://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git/ Pull 'uverbs_dev_cleanups' from Leon Romanovsky: ==================== Reuse the char device code interfaces to simplify ib_uverbs_device creation and destruction. As part of this series, we are sending fix to cleanup path, which was discovered during internal review, The fix definitely can go to -rc, but it means that this series will be dependent on rdma-rc. ==================== * branch 'uverbs_dev_cleanups': RDMA/uverbs: Use device.groups to initialize device attributes RDMA/uverbs: Use cdev_device_add() instead of cdev_add() RDMA/core: Depend on device_add() to add device attributes RDMA/uverbs: Fix error cleanup path of ib_uverbs_add_one() Resolved conflict in ib_device_unregister_sysfs() Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
