f4f52873a1 staging: r8188eu: always process urb status
Remove the if clause in usb_write_port_complete and process the urb
status regardless of bSurpriseRemoved, bDriverStopped and
bWritePortCancel.

The only possible results of urb status processing are updates to
bSurpriseRemoved and bDriverStopped. All of the three status variable are
set to true only if the whole USB processing has to be stopped (when the
driver is unloaded or when the system goes to sleep).

It's no problem if one of the "stop everything" variables is already set
and the urb status processing sets another one.

This patch removes the last goto in usb_write_port_complete. It's also
part of the ongoing effort to limit the use of the "stop everything"
variables.

The _rtw_init_xmit_priv function calls rtw_alloc_hwxmits to allocate
memory for pxmitpriv->hwxmits (this is an array of struct hw_xmit). This

After the allocation, _rtw_init_xmit_priv calls rtw_init_hwxmits to set an
element of each hw_xmit to 0. This is not necessary, we can remove the
rtw_init_hwxmits call and the now unused function rtw_init_hwxmits.

a6b25e291f staging: r8188eu: simplify rtw_make_wlanhdr's error handling
Simplify the error handling in rtw_make_wlanhdr. Exit immediately instead
of jumping to the end of the function. We don't have to do any clean-up.

e263d79eb1 staging: r8188eu: simplify frame type check
Reorder the code in rtw_make_wlanhdr to make the function simpler.
There's a large if statement to check that we process only data frames.
Revert the condition and exit for non-data frames.

Remove rtl8188eu_init_xmit_priv and initialise the xmit tasklet in

xmit_buf internally.
