[PATCH] ath11k: fix error handling in ath11k_qmi_assign_target_mem_chunk()

From: trix
Date: Sun Jan 16 2022 - 09:43:52 EST


From: Tom Rix <trix@xxxxxxxxxx>

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")
