Subject: [PATCH][next] carl9170: Replace zero-length array with DECLARE_FLEX_ARRAY() helper
Date: Mon, 26 Sep 2022 16:44:57 -0500 [thread overview]
Message-ID: <YzIdWc8QSdZFHBYg@work> (raw)
Zero-length arrays are deprecated and we are moving towards adopting
C99 flexible-array members, instead. So, replace zero-length arrays
declarations in anonymous union with the new DECLARE_FLEX_ARRAY()
helper macro.
This helper allows for flexible-array members in unions.
