Re: [PATCH] Fix build warning: Implicit declaration nxsem_post()

[Gregory Nutt]

Recently this warning started showing up in builds:

icmp/icmp_netpoll.c: In function 'icmp_poll_eventhandler':
icmp/icmp_netpoll.c:129:11: warning: implicit declaration of function
'nxsem_post'; did you mean 'sem_post'?
[-Wimplicit-function-declaration]
            nxsem_post(info->fds->sem);
            ^~~~~~~~~~
            sem_post

I am doing a build test now.  Yes, I am seeing this new warning too (A 
LOT).  But I am also seeing 'ret may be used uninitialized in this 
function" in the return value of icmp_pollsetup() in the same file, 
icmp/icmp_netpoll.c
