This is just a cleanup and doesn't change how the code works.
debugfs_create_dir() and debugfs_create_file() return an error pointer
(-ENODEV) if CONFIG_DEBUG_FS is not enabled, otherwise if an error occurs
they return NULL. This is how they are implemented and what it says in
the DebugFS documentation. DebugFS can not be compiled as a module.
As a result, we only need to check for error pointers and particularly
-ENODEV one time to know that DebugFS is enabled. This patch keeps the
first check for error pointers and removes the rest.
The other reason for this patch, is that it silences some Smatch warnings.
Smatch sees the condition "(result != -ENODEV)" and assumes that it's

to an error pointer dereference. But since it's not, we can just remove

mac80211: fix rts threshold check
Currently whenever rts thresold is set, every packet will use RTS
protection no matter its size exceeds the threshold or not. This is
due to a bug in the rts threshold check.
if (len > tx->local->hw.wiphy->rts_threshold) {
txrc.rts = rts = true;
}
Basically it is comparing an int (len) and a u32 (rts_threshold),
and the variable len is assigned as:
len = min_t(int, tx->skb->len + FCS_LEN,
tx->local->hw.wiphy->frag_threshold);
However, when frag_threshold is "-1", len is always "-1", which is
0xffffffff therefore rts is always set to true.
