Subject: [PATCH] ASoC: cs-amp-lib: Annotate struct cirrus_amp_efi_data with __counted_by()
Date: Tue, 15 Apr 2025 11:03:55 +0200 [thread overview]
Message-ID: <20250415090354.92211-2-thorsten.blum@linux.dev> (raw)
Add the __counted_by() compiler attribute to the flexible array member
'data' to improve access bounds-checking via CONFIG_UBSAN_BOUNDS and
CONFIG_FORTIFY_SOURCE.
No functional changes intended.
