Hi,

i'm currently working on Raspberry Pi Zero W for Mainline. Here is my first patch series [1].

Unfortunately i didn't get brcmfmac (connected via SDIO) probed with this patch series against 4.12.0-rc5-next-20170616+

...
Can you please try to comment out the following lines in
brcmf_feat_attach? That's the only suspicious line that interact with
firmware in the patch.

+ brcmf_feat_iovar_data_set(ifp, BRCMF_FEAT_GSCAN, "pfn_gscan_cfg",
+                                            &gscan_cfg, sizeof(gscan_cfg));

after commenting out this line, the issue doesn't appear.

what are the plans to fix this regression?
