[ Upstream commit cb4c132ebfeac5962f7258ffc831caa0c4dada1a ]
When compiling with clang 16.0.6 and CONFIG_FORTIFY_SOURCE=y, I've
noticed the following (somewhat confusing due to absence of an actual
source code location):
In file included from drivers/net/wireless/ath/ath10k/debug.c:8:

The compiler actually complains on 'ath10k_debug_get_et_strings()' where
fortification logic inteprets call to 'memcpy()' as an attempt to copy
the whole 'ath10k_gstrings_stats' array from it's first member and so
issues an overread warning. This warning may be silenced by passing
an address of the whole array and not the first member to 'memcpy()'.

The compiler actually complains on 'ath9k_get_et_strings()' and
'ath9k_htc_get_et_strings()' due to the same reason: fortification logic
inteprets call to 'memcpy()' as an attempt to copy the whole array from
it's first member and so issues an overread warning. These warnings may
be silenced by passing an address of the whole array and not the first
member to 'memcpy()'.

In 'rtl92c_dm_check_edca_turbo()', 'rtl88e_dm_check_edca_turbo()',
and 'rtl8723e_dm_check_edca_turbo()', the DL limit should be set
from the corresponding field of 'rtlpriv->btcoexist' rather than
UL. Compile tested only.

Since debugfs_create_file() return ERR_PTR and never return NULL, so use
IS_ERR() to check it instead of checking NULL.
