A sysfs file is a special file which prints an EOF at any
reading. Therefore it's not possible to open it once, read it
whenever is needed (since an EOF is received after the first
reading) and then close it.
The sequence
fd = open(pathname, flags);
while (1)
read(fd, buf, count);
close(fd);
should be
while (1) {
fd = open(pathname, flags);
read(fd, buf, count);
close(fd);
}

This patch fixes one of the most common errors about errno usage:
if (somecall() == -1) {
printf("somecall() failed\n");
if (errno == ...) { ... }
}
printf may change the value of errno, so that the errno value in
the if statement is not anymore referring to 'somecall()'
function.
The correct usage should be:
if (somecall() == -1) {
int errsv = errno;
printf("somecall() failed\n");
if (errsv == ...) { ... }
}

Files are in
/sys/class/i2c-adapter/i2c-12/12-0039/
instead of
/sys/class/i2c-adapter/i2c-0012/12-0039/
^^
The above '0's are a typo

The bh1770glc is a combined proximity/als sensor. The module in
this patch tests the proximity part of the device. At the current
status the test steps are:
- power on the bh1770 sensor
- enable proximity leds
- read proximity
- disable proximity
- power off the sensor

apds990x is a combined proximity/als sensor. The test provides a
basic test for the als part.
The following are the testing steps:
- power on the sensor
- read 10 times the lux value on 1 second interval
