Hans Verkuil | 6ca187a | 2009-01-15 05:53:18 -0300 | [diff] [blame] | 1409 | Without this the audio standard detection will fail and you will |
| 1410 | only get mono. |
| 1411 | |
| 1412 | Since loading the firmware is often problematic when the driver is |
| 1413 | compiled into the kernel I recommend postponing calling this function |
| 1414 | until the first open of the video device. Another reason for |
| 1415 | postponing it is that loading this firmware takes a long time (seconds) |
| 1416 | due to the slow i2c bus speed. So it will speed up the boot process if |
| 1417 | you can avoid loading the fw as long as the video device isn't used. */ |
