From e264a3dbe866870ed21ef83c67ad956a45391859 Mon Sep 17 00:00:00 2001 From: Miaoqing Pan Date: Sat, 9 May 2026 10:58:16 +0800 Subject: [PATCH] wifi: ath12k: refactor HAL TLV32/64 decode helpers Change TLV decode helpers to return the TLV value pointer and optionally decode tag/len/usrid via out parameters. This allows reusing the helpers for DP monitor RX status header TLV parsing and avoids duplicated header decoding in callers. No functional change intended.
