[PATCH 2/7] selftest/timers: Quiet warning due to lack of return check on brk

[John Stultz]

The posix_timers.c test has a loop that tries to keep it in
kernel space, repeatedly calling brk(). Since its noise, and
a failure won't change what the test would do, add a unused
value to quiet the warning.
