Subject: [PATCH] ath11k: fix error handling in ath11k_qmi_assign_target_mem_chunk()
Date: Sun, 16 Jan 2022 06:42:06 -0800 [thread overview]
Message-ID: <20220116144206.399385-1-trix@redhat.com> (raw)
From: Tom Rix <trix@redhat.com>
Clang static analysis reports this problem
qmi.c:1935:5: warning: Undefined or garbage value returned to caller
return ret;
^~~~~~~~~~
ret is uninitialized. When of_parse_phandle() fails, garbage is
returned. So return -EINVAL.
Fixes: 6ac04bdc5edb ("ath11k: Use reserved host DDR addresses from DT for PCI devices")
Signed-off-by: Tom Rix <trix@redhat.com>
