Clang detected this macro expansion bug: drivers/staging/rtl8192u/r8192U_core.c:2384:76: warning: operator '?:' has lower precedence than '+'; '+' will be evaluated first [-Wparentheses] The line from the .c file looks like this: u1bAIFS = qos_parameters->aifs[i] * ((mode&(IEEE_G|IEEE_N_24G)) ?9:20) + aSifsTime; We need to put parenthesis around the entire macro to fix the bug.
