cfg80211_ops.set_monitor_channel() gained a "struct net_device *dev"
parameter in mainline 6.13, and the change was backported to the 6.12
stable series starting with 6.12.101. Debian 13 ships 6.12.107, so the
existing ">= 6.13.0" guards select the old prototype there and the build
fails with -Wincompatible-pointer-types:
rwnx_main.c: error: initialization of
'int (*)(struct wiphy *, struct net_device *, struct cfg80211_chan_def *)'
from incompatible pointer type
'int (*)(struct wiphy *, struct cfg80211_chan_def *)'
[-Wincompatible-pointer-types]
This is the failure reported in #96 for Debian 13 trixie.
Introduce AICWF_CFG80211_SET_MONITOR_CHANNEL_HAS_DEV in rwnx_compat.h,
defined at AICWF_CFG80211_VERSION_CODE >= 6.12.101, and gate the nine
set_monitor_channel call sites on it instead of comparing against 6.13.0.
The threshold covers both the 6.12 backport and mainline 6.13, while
kernels 6.11 and earlier 6.12.x keep the old prototype. The check now
lives in one place and follows the existing AICWF_CFG80211_VERSION_CODE
convention, so OpenWrt builds can override it with CFG80211_VERSION.
The MODULE_IMPORT_NS guard at rwnx_main.c that also checks 6.13.0 is
unrelated and is left untouched.
Verified with clean builds against linux-headers 5.15.0-191,
6.1.0-53, 6.8.0-139, 6.11.0-8 and 6.12.107+deb13.
