airspy: increase USB control message buffer size

2016-01-31T19:25:48Z

commit aa0850e1d56623845b46350ffd971afa9241886d upstream. Driver requested device firmware version string during probe using only 24 byte long buffer. That buffer is too small for newer firmware versions, which causes device firmware hang - device stops responding to any commands after that. Increase buffer size to 128 which should be enough for any current and future version strings.

[media] airspy: enhance sample rate debug calculation precision

2014-09-21T19:42:33Z

Sample rate calculation gives a little bit too large results because in real life there was around one milliseconds (~one usb packet) too much data for given time. Calculate time more accurate in order to provide better results. Signed-off-by: Antti Palosaari Signed-off-by: Mauro Carvalho Chehab

[media] airspy: remove unneeded spinlock irq flags initialization

2014-09-21T19:42:33Z

There is no need to init flags before calling spin_lock_irqsave(). spin_lock_irqsave is a macro which stores value to 'flags'. Signed-off-by: Antti Palosaari Signed-off-by: Mauro Carvalho Chehab

[media] airspy: logging changes

2014-09-21T19:42:32Z

Kernel logging system needs pointer to usb interface device in order to print names and bus numbers properly. There was wrong device pointer given and log printings wasn't correct. Remove some debug logging from v4l2 ioctl functions. v4l2 core debug prints almost same information when enabled. Signed-off-by: Antti Palosaari Signed-off-by: Mauro Carvalho Chehab
