Akihiro Tsukada 87360e68b3 media: dvb-usb-v2/gl861: use usleep_range() for short delay
As the kernel doc "timers-howto.txt" reads,
short delay with msleep() can take much longer.
In a case of raspbery-pi platform where CONFIG_HZ_100 was set,
it actually affected the init of Friio devices
since it issues lots of i2c transactions with short delay.
