This does not blow up because we only have a limited number of items so we never recurse too deep. But the recursion is still quite ugly and frankly is giving me a headache, so lets fix this. This commit fixes this by removing brcmf_fw_request_next_item and by making brcmf_fw_get_firmwares and brcmf_fw_request_done directly call firmware_request_nowait resp. firmware_request themselves. *) brcmf_fw_request_nvram_done fallback path succeeds or BRCMF_FW_REQF_OPTIONAL is set Signed-off-by: Hans de Goede --- .../broadcom/brcm80211/brcmfmac/firmware.c | 65 ++++++------------- 1 file changed, 19 insertions(+), 46 deletions(-) diff --git a/drivers/net/wireless/broadcom/brcm80211/brcmfmac/firmware.c b/drivers/net/wireless/broadcom/brcm80211/brcmfmac/firmware.c index 784c84f0e9e7..08aaf99fee34 100644 --- a/drivers/net/wireless/broadcom/brcm80211/brcmfmac/firmware.c +++ b/drivers/net/wireless/broadcom/brcm80211/brcmfmac/firmware.c @@ -532,33 +532,6 @@ static int brcmf_fw_complete_request(const struct firmware *fw, return (cur->flags & BRCMF_FW_REQF_OPTIONAL) ? 0 : ret; } -static int brcmf_fw_request_next_item(struct brcmf_fw *fwctx, bool async) -{ - struct brcmf_fw_item *cur; - const struct firmware *fw = NULL; - int ret; - - cur = &fwctx->req->items[fwctx->curpos]; - - brcmf_dbg(TRACE, "%srequest for %s\n", async ?

To be able to distribute these as part of linux-firmware, so that devices with such a wifi chip will work OOTB, multiple (one per board) versions must co-exist under /lib/firmware. This commit adds support for callers of the brcmfmac/firmware.c code to pass in a board_type parameter through the request structure. If that parameter is set then the code will first try to load chipmodel.board_type.txt before falling back to the old chipmodel.txt name.
