[PATCH 0/2] Deduplicate bin_attribute simple read() callbacks

[Lukas Wunner]

For my upcoming PCI device authentication v2 patches, I have the need
to expose a simple buffer in virtual memory as a bin_attribute.

It turns out we've duplicated the ->read() callback for such simple
buffers a fair number of times across the tree.

So instead of reinventing the wheel, I decided to introduce a common
helper and eliminate all duplications I could find.

I'm open to a bikeshedding discussion on the sysfs_bin_attr_simple_read()
name. ;)

  sysfs: Add sysfs_bin_attr_simple_read() helper
  treewide: Use sysfs_bin_attr_simple_read() helper
