ringtools/imy: fix duplicate definition of tdma_durations[] The bug was reported by Vadim Yanitskiy <fixeria@osmocom.org>, although the present fix is slightly different from the contributed patch: because main.c doesn't need this tdma_durations[] array at all, let's simply remove the reference to this array from main.c rather than turn it into an extern. I no longer remember my original thought flow that resulted (by mistake) in tdma_durations[] being multiply defined in main.c and durations.c. My intent might have been to define all globals in main.c and have the reference in durations.c be an extern - and I missed that extern - but without clear memory, I have no certainty. In any case, having this data array defined in the same module that fills it (durations.c) is sensible, so let's make it the new way.

/*
 * This header file defines the loop-count timeout value that should
 * be passed to the rx_sim_byte() function.  By the spec we have to wait
 * 9600 etu's; at 3.25 MHz SIM clock and the default slow mode (no speed
 * enhancement) this 9600 etu number translates to about 1.10 s.
 *
 * The constant defined here has been calibrated empirically; the measured
 * timeout is about 1.38 s, giving us reasonable safety margin.
