1410 | Since loading the firmware is often problematic when the driver is | |
1411 | compiled into the kernel I recommend postponing calling this function | |
1412 | until the first open of the video device. Another reason for | |
1413 | postponing it is that loading this firmware takes a long time (seconds) | |
1414 | due to the slow i2c bus speed. So it will speed up the boot process if | |
1415 | you can avoid loading the fw as long as the video device isn't used. */ | |
