Subject: [PATCH][next] wifi: wil6210: wmi: Replace zero-length array with DECLARE_FLEX_ARRAY() helper
Date: Mon, 15 May 2023 13:25:39 -0600 [thread overview]
Message-ID: <ZGKHM+MWFsuqzTjm@work> (raw)
Zero-length arrays are deprecated, and we are moving towards adopting
C99 flexible-array members, instead. So, replace zero-length arrays
declarations alone in structs with the new DECLARE_FLEX_ARRAY()
helper macro.
This helper allows for flexible-array members alone in structs.
