Remove unnecessary if and else conditions since both are leading to the
initialization of "phtpriv->ampdu_enable" with the same value.
Also, remove the unnecessary else-if condition since it does nothing.

Changes in v2
- Remove unnecessary comments
- Remove unnecessary else-if condition which does nothing.

This isn't the same test.
This could be:
if ((!(phtpriv->ampdu_enable) && pregistrypriv->ampdu_enable == 1)) ||
pregistrypriv->ampdu_enable == 2)
phtpriv->ampdu_enable = true;
Though it is probably more sensible to just set
phtpriv->ampdu_enable without testing whether or
not it's already set:
if (pregistrypriv->ampdu_enable == 1 ||
pregistrypriv->ampdu_enable == 2)
phtpriv->ampdu_enable = true;

But the else-if block which I removed in v2 of this patch had nothing
in the block.
It was not assigning any value to "phtpriv->ampdu_enable". ( basically
it was empty and useless)
Now as per your suggestion if I do the change then the value of
"phtpriv->ampdu_enable" will be changed to true when we have
"pregistrypriv->ampdu_enable == 2" condition. But in real it should be
the same as it was by default coming from the start of the function.
( This is because the else-if block was empty and doing nothing )
Please let me know if I was able to make you understand my point of
view here. Also, please correct me if I am wrong.
Thanks

I suspect this is actually a bug, that is:
os_dep/os_intfs.c:74:static int rtw_ampdu_enable = 1;/* for enable tx_ampdu ,0: disable, 0x1:enable (but wifi_spec should be 0), 0x2: force enable (don't care wifi_spec) */
and that seems to actually map to the ampdu_enable field in
pregistrypriv.
However, I wouldn't change this without testing it on the actual
hardware, change looks good to me and doesn't affect functionality,
