Subject: [PATCH 2/6][next] cfg80211: Avoid clashing function prototypes
When built with Control Flow Integrity, function prototypes between
caller and function declaration must match. These mismatches are visible
at compile time with the new -Wcast-function-type-strict in Clang[1].
Fix a total of 10 warnings like these:
../drivers/net/wireless/intersil/orinoco/wext.c:1390:27: error: incompatible function pointer types initializing 'const iw_handler' (aka 'int (*const)(struct net_device *, struct iw_request_info *, union iwreq_data *, char *)') with an expression of type 'int (struct net_device *, struct iw_request_info *, struct iw_param *, char *)' [-Wincompatible-function-pointer-types]
IW_HANDLER(SIOCGIWRETRY, cfg80211_wext_giwretry),
^~~~~~~~~~~~~~~~~~~~~~
../include/uapi/linux/wireless.h:357:23: note: expanded from macro 'IW_HANDLER'
[IW_IOCTL_IDX(id)] = func
The cfg80211 Wireless Extension handler callbacks (iw_handler) use a
union for the data argument. Actually use the union and perform explicit
member selection in the function body instead of having a function
prototype mismatch. No significant binary differences were seen
before/after changes.
