[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
