6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matvey Kovalev matvey.kovalev@ispras.ru
commit 3fd2ef2ae2b5c955584a3bee8e83ae7d7a98f782 upstream.
If ab->fw.m3_data points to data, then fw pointer remains null. Further, if m3_mem is not allocated, then fw is dereferenced to be passed to ath11k_err function.
Replace fw->size by m3_len.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
