  wifi: rtl8xxxu: Fix reads of uninitialized variables hw_ctrl_s1, sw_ctrl_s1 (2022-10-21 15:54:06 +0300)

----------------------------------------------------------------
wireless-next patches for v6.2

First set of patches v6.2. mac80211 refactoring continues for Wi-Fi 7.
All mac80211 driver are now converted to use internal TX queues, this
might cause some regressions so we wanted to do this early in the
cycle.

Note: wireless tree was merged[1] to wireless-next to avoid some
conflicts with mac80211 patches between the trees. Unfortunately there
are still two smaller conflicts in net/mac80211/util.c which Stephen
also reported[2]. In the first conflict initialise scratch_len to
"params->scratch_len ?: 3 * params->len" (note number 3, not 2!) and
in the second conflict take the version which uses elems->scratch_pos.

Git diff output should like this:
