Merge branch 'driver-core-linus' into driver-core-next
a8b14744429f ("sysfs: give different locking key to regular and bin files") in driver-core-linus modifies sysfs_open_file() so that it gives out different locking classes to sysfs_open_files depending on whether the file is bin or not. Due to the massive kernfs reorganization in driver-core-next, this naturally causes merge conflict in fs/sysfs/file.c. Due to the way things are split between kernfs and sysfs in driver-core-next, the same fix can't easily be applied to driver-core-next. This merge simply ignores the offending commit. A following patch will implement a separate fix for the issue. Signed-off-by: Tejun Heo <tj@kernel.org>
