[PATCH 18/22] nvmem: u-boot-env:: Replace zero-length array with DECLARE_FLEX_ARRAY() helper

From: Srinivas Kandagatla
Date: Mon Aug 14 2023 - 12:54:58 EST


From: Atul Raut <rauji.raut@xxxxxxxxx>

We are moving toward replacing zero-length arrays with C99 flexible-array
members since they are deprecated. Therefore, the new DECLARE_FLEX_ARRAY()
helper macro should be used to replace the zero-length array declaration.

This fixes warnings such as:
./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)
