- 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:
