SubjectRE: [PATCH] wireless: mwifiex: remove unreachable paths
Hi Sasha,

Thanks for the patch.

> We know 'firmware' is non-NULL from the beginning of mwifiex_prog_fw_w_helper,
> remove all !firmware paths from the rest of the function.

After removing all !firmware paths the function 'mwifiex_get_fw_data' becomes an orphan.

Could you please remove that function as well and resend a v2 patch?

Thanks,
Bing
