Hmm. vgic_v3_setup() return gic_fd looks like and the interface says
Return: GIC file-descriptor or negative error code upon failure
Yes, but in reality the only return other than a valid file descriptor
is just -1 rather than a useful error code.
The interface document gives the impression that it will return
error - Oh well. In which case, no point in printing that. Agree.
I don't follow the abort part.
All the TEST_ASSERTS() in the code (including those in the functions
called) are calls to test_assert() in assert.c which if the test
asserted isn't true will print some diagnostics and call exit(), the
general idiom is to give up immediately on error.
Ah right. Makes sense.
