Merge tag 'thunderbolt-for-v5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/westeri/thunderbolt into usb-next
Mika writes:
thunderbolt: Changes for v5.7 merge window
- A couple of commits that make the driver to use flexible-array member
instead of zero-length array extension. This allows compiler to issue a
warning if the flexible array is not the last member of a structure.
- Use scnprintf() instead of snprintf() to avoid potential buffer
overflow.
