4 Subject: [PATCH] brcmfmac: introduce brcmf_fw_alloc_request() function
5
6 The function brcmf_fw_alloc_request() takes a list of required files
7 and allocated the struct brcmf_fw_request instance accordingly. The
8 request can be modified by the caller before being passed to the
9 brcmf_fw_request_firmwares() function.
