Subject[PATCH] staging/greybus: eliminate use of NAME_SIZE for strings
Date
Instead, depend on the size of the destination buffer for easier
refactoring.

Signed-off-by: Kumar Kartikeya Dwivedi <memxor@gmail.com>

Hopefully, this is more thorough. The only cases left now are where the
destination string is represented by a pointer, otherwise all call sites with a
fixed sized buffer have been changed.
