[v2,0/6] Avoid clashing function prototypes

Message

Gustavo A. R. Silva Oct. 27, 2022, 8:16 p.m. UTC

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].

This series fixes a total of 424 -Wcast-function-type-strict warnings.

Changes in v2:
 - Squash previous patches 1, 2 and 3 into a single patch
   cfg80211.
 - Add a couple more patches: bna and staging.
 - Fix 254 (227 in bna and 27 in staging) more
   -Wcast-function-type-strict warnings.

v1:
