RetroArch/input/input_driver.c
gblues 1beba28d02 Only call HIDSetup/HidTeardown once 
== DETAILS
I did a minimalist edit of the HID thread that stripped out all
HID* syscalls, and this stopped the crashing. I then re-added just
the HIDSetup() and HIDTeardown() calls, and the crash came back.

This smells like an OS bug. To work around it, I've put the
HIDSetup() and HIDTeardown() calls into the app init/shutdown
section, so they only get called once in the application lifetime
and not each time the input driver is initialized.
