[PATCH v4 1/4] mwifiex: remove unnecessary wakeup interrupt number sanity check

[Xinming Hu]

From: Xinming Hu <huxm@marvell.com>

If wakeup interrupt handler is called, we know that the wakeup
interrupt number is valid, there is no need to check it.

[PATCH v4 4/4] mwifiex: pcie: extract wifi part from combo firmware during function level reset

[Xinming Hu]

From: Xinming Hu <huxm@marvell.com>

A seprate wifi-only firmware was download during pcie function level reset.
It is in fact the tail part of wifi/bt combo firmware. Per Brian's and
Dmitry's suggestion, this patch extract the wifi part from combo firmware.

After that, we can discard the redudant image in linux-firmware repo.

If you mean with discarding removing the actual image from
linux-firmware, then you cannot do that. The image is still needed so
that linux-firmware works with older kernels.

Please don't add my Reviewed-by tag unless I've provided it explicitly.
And especially not if you have to change the patch significantly. (It's
fair to carry an old tag I've provided, if you only have to make minor
changes, or if I suggest *exactly* what needs changed, along with a
conditional 'Reviewed-by'.)

As it stands, this patch is worse than the previous one. I replied to
some of your commnets on v3, but I'll carry some here.

This is worse than what you used to have. This should still be:

		if (offset + sizeof(fwdata->header) >= firmware_len) {

And you might add an overflow check here too, so:

		/* Check for integer and buffer overflow */
		if (offset + sizeof(fwdata->header) < sizeof(fwdata->header) ||
		    offset + sizeof(fwdata->header) >= firmware_len) {

> +			mwifiex_dbg(adapter, ERROR,

Needs a '\n'.

> +		dnld_cmd = le32_to_cpu(fwdata->header.dnld_cmd);
> +		data_len = le32_to_cpu(fwdata->header.data_length);

Then:

		offset += sizeof(fwdata->header);

Replace with:

			if (offset + data_len < data_len) {
				mwifiex_dbg(adapter, ERROR, "bad firmware\n");
				ret = -1;
				goto done;
			}
			offset += data_len;

> +			break;
> +		case MWIFIEX_FW_DNLD_CMD_5:

Replace with:

			if (offset + data_len < data_len) {
				mwifiex_dbg(adapter, ERROR, "bad firmware\n");
				ret = -1;
				goto done;
			}
			offset += data_len;

> +			break;

Replace with:

Now you can delete this line.

I might just rewrite this and send it myself, if I get the time.

[PATCH v5 4/4] mwifiex: pcie: extract wifi part from combo firmware during function level reset

[Brian Norris]

From: Xinming Hu <huxm@marvell.com>

A separate wifi-only firmware was download during pcie function level
reset. It is in fact the tail part of wifi/bt combo firmware. Per
Brian's and Dmitry's suggestion, this patch extract the wifi part from
combo firmware.

After that, the mrvl/pcie8997_wlan_v4.bin image in linux-firmware repo
is redundant (though I guess we keep it around to support older
kernels).

Done.

v2: extract wifi part from combo firmware(Dmitry and Brian)
    add more description(Kalle)
v3: same as v2
v4: add sequence comments, code enhance(Brian)
v5: (Brian) fix overflow errors
    (Brian) add missing newline chars
    (Brian) consolidate header-skipping logic

Note: I only resubmitted the 4th patch, as the others look fine
