Subject: [PATCH ath-next] wifi: ath9k: mark PN9Data as const
Date: Mon, 15 Jun 2026 20:06:52 -0700 [thread overview]
Message-ID: <20260616030652.635121-1-rosenp@gmail.com> (raw)
PN9Data is a read-only lookup table and is never modified. Adding const
lets the compiler place it in .rodata and prevents accidental writes.
