clocksource/fsl: Avoid harmless 64-bit warnings The ftm_clockevent_init passes the value of "~0UL" into a function that takes a 32-bit argument, which drops the upper 32 bits, as gcc warns about on ARM64: clocksource/fsl_ftm_timer.c: In function 'ftm_clockevent_init': clocksource/fsl_ftm_timer.c:206:13: warning: large integer implicitly truncated to unsigned type [-Woverflow] This was obviously unintended behavior, and is easily avoided by using '~0u' as the integer literal, because that is 32-bit wide on all architectures.
