Subject: fix bug from syscall overhaul: extra __syscall_ret call for 0-arg syscalls
X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=4cc78719dd22a685ddd89b92ac3bfc308c4c19b3

fix bug from syscall overhaul: extra __syscall_ret call for 0-arg syscalls

this mainly just caused bloat, but could corrupt errno if a 0-arg
syscall ever failed.
