+Subject: [PATCH] brcmfmac: support repeated brcmf_fw_alloc_request() calls
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+During a normal brcmfmac lifetime brcmf_fw_alloc_request() is called
+once only during the probe. It's safe to assume provided array is clear.
+
+Further brcmfmac improvements may require calling it multiple times
+though. This patch allows it by fixing invalid firmware paths like:
