The arguments that were passed into sizeof were

the actual item that we need a size of instead.

For example:

Parse struct vnt_tx_datahead_g from s_uFillDataHead and
move to struct vnt_rts_g/struct vnt_cts structure.

This removes pvTxDataHd pointer assignment.

The duration_id(uDuration) field is now returned in s_vGenerateTxParameter.

The return of s_uFillDataHead temporary or'ed to retain functionality of

Since pvTxDataHd is now null a small vendor hack to vDMA0_tx_80211/csMgmt_xmit
to do with Disassociation-packet is also changed correct head position.

staging: dwc2: Make dwc2_hw_params.host_channels large enough

The hardware offers a 4-bit register containing the number of host
channels. However, the values of these register mean 1-16 host channels,
not 0-15. Since the dwc2_hw_params struct stores the actual number of
host channels supported instead of the raw register value, it should be
5 bits wide instead of 4.

Before this commit, hardware with 16 host channels would overflow the
field, making it appear as 0 channels.

This bug was introduced in commit 9badec2 (staging: dwc2: interpret all
hwcfg and related register at init time).
