sched/signal: Fix nxsig_ismember() return value behavior
Build Documentation / build-html (push) Has been cancelled
Details

Browse Source 
nxsig_ismember() has a return type of int, but the current
implementation returns a boolean value, which is incorrect.

All callers should determine membership by checking whether
the return value is 1 or 0, which is also consistent with the POSIX sigismember() API.
