[PATCH] wireless: mwifiex: remove unreachable paths

[Sasha Levin]

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.

RE: [PATCH] wireless: mwifiex: remove unreachable paths

[Bing Zhao]

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

Hi Sasha,

I have no problem with this cosmetic change, but it should probably be
sent to net-next when it is open again. When you do resubmit it, you can
add my ACK:

Applied.
