Subject: [PATCH 0/6] Deduplicate string exposure in sysfs

Introduce a generic ->show() callback to expose a string as a device
attribute in sysfs.  Deduplicate various identical callbacks across
the tree.

Result:  Minus 216 LoC, minus 1576 bytes vmlinux size (x86_64 allyesconfig).

This is a byproduct of my upcoming PCI device authentication v2 patches.

Lukas Wunner (6):
  driver core: Add device_show_string() helper for sysfs attributes
  hwmon: Use device_show_string() helper for sysfs attributes
  IB/qib: Use device_show_string() helper for sysfs attributes
  perf: Use device_show_string() helper for sysfs attributes
  platform/x86: Use device_show_string() helper for sysfs attributes
  scsi: Use device_show_string() helper for sysfs attributes
