We've been declaring a bunch of statically-sized arrays:
extern struct foo_t foo[FOO_COUNT];
And then initializing them like so:
struct foo_t foo[FOO_COUNT] = {
/* blah */
};
That only catches cases where we initialize with too many entries. It
doesn't catch cases where we haven't initialized enough. This change tests
for both cases like so:
extern struct foo_t foo[];
struct foo_t foo[] = {
/* blah */
};
BUILD_ASSERT(ARRAY_SIZE(foo) == FOO_COUNT);
The affected arrays are:
adc_channels[ADC_CH_COUNT]
gpio_list[GPIO_COUNT]
temp_sensors[TEMP_SENSOR_COUNT]
x86_signal_list[X86_SIGNAL_COUNT]
i2c_ports[I2C_PORTS_USED]
BUG=chrome-os-partner:18343
BRANCH=falco,peppy
TEST=build all platforms
All platforms should still build, all tests should still pass.
