7419d8ab35 wifi: rtlwifi: rtl92ee_dm_dynamic_primary_cca_check(): fix typo in function name
For rtl8192ee, change 'rtl92ee_dm_dynamic_primary_cca_ckeck()'
to 'rtl92ee_dm_dynamic_primary_cca_check()' and so adjust
'rtl92ee_dm_watchdog()' as well. Compile tested only.

The root cause of the problem is that the comparison order of
"prate_section" in _rtl8812ae_phy_set_txpower_limit() is wrong. The
_rtl8812ae_eq_n_byte() is used to compare the first n bytes of the two
strings from tail to head, which causes the problem. In the
_rtl8812ae_phy_set_txpower_limit(), it was originally intended to meet
this requirement by carefully designing the comparison order.
For example, "pregulation" and "pbandwidth" are compared in order of
length from small to large, first is 3 and last is 4. However, the
comparison order of "prate_section" dose not obey such order requirement,
therefore when "prate_section" is "HT", when comparing from tail to head,
it will lead to access out of bounds in _rtl8812ae_eq_n_byte(). As
mentioned above, the _rtl8812ae_eq_n_byte() has the same function as
strcmp(), so just strcmp() is enough.

Fix it by removing _rtl8812ae_eq_n_byte() and use strcmp() barely.
Although it can be fixed by adjusting the comparison order of
"prate_section", this may cause the value of "rate_section" to not be
from 0 to 5. In addition, commit "21e4b0726dc6" not only moved driver
from staging to regular tree, but also added setting txpower limit
function during the driver config phase, so the problem was introduced
by this commit.

93fbc1ebd9 wifi: rtlwifi: 8192de: correct checking of IQK reload
Since IQK could spend time, we make a cache of IQK result matrix that looks
like iqk_matrix[channel_idx].val[x][y], and we can reload the matrix if we
have made a cache. To determine a cache is made, we check
iqk_matrix[channel_idx].val[0][0].

The initial commit 7274a8c229 ("rtlwifi: rtl8192de: Merge phy routines")
make a mistake that checks incorrect iqk_matrix[channel_idx].val[0] that
is always true, and this mistake is found by commit ee3db469dd
("wifi: rtlwifi: remove always-true condition pointed out by GCC 12"), so
I recall the vendor driver to find fix and apply the correctness.

b88d28146c wifi: rtlwifi: fix error codes in rtl_debugfs_set_write_h2c()
If the copy_from_user() fails or the user gives invalid date then the
correct thing to do is to return a negative error code.  (Currently it
returns success).

I made a copy additional related cleanups:
1) There is no need to check "buffer" for NULL.  That's handled by
copy_from_user().
2) The "h2c_len" variable cannot be negative because it is unsigned
and because sscanf() does not return negative error codes.
