Subject: posix-timers: Define nanosleep not supported error separate
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=65da528d7cc94966cf24d2a1e0837b689159b543;p=mv-sheeva.git

posix-timers: Define nanosleep not supported error separate

Define the conditional nanosleep not supported error value outside of
do_posix_clock_nonanosleep(). Preparatory patch for further cleanups.
