   4 Subject: [PATCH] nvmem: u-boot-env:: Replace zero-length array with
   5  DECLARE_FLEX_ARRAY() helper
   6
   7 We are moving toward replacing zero-length arrays with C99 flexible-array
   8 members since they are deprecated. Therefore, the new DECLARE_FLEX_ARRAY()
   9 helper macro should be used to replace the zero-length array declaration.
  10
  11 This fixes warnings such as:
  12 ./drivers/nvmem/u-boot-env.c:50:9-13: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)
