This cleans-up the advise/acquire methods. This has been tested on the hvr-1300/4000 and assumed to be correct on the hvr-3000. This update also fixes analogue tuning on the hvr-1300 when in blackbird mode. Signed-off-by:

It has been noticed that in HW tuning mode in cx24123.c that a check is made to not alter the status var when in one shot mode, a simpler solution is to not update here for all cards. Cc: Steven Toth <stoth@hauppauge.com> Signed-off-by:

tuner-xc3028 can be put to sleep to save power. However, if not properly recovered from sleep, the device won't work. It is noticed that some devices doesn't recover properly, so let's add a dump_stack() as a debug option, to allow us to track when this happens. Signed-off-by: -

Changes/fixes on em28xx dev->lock: - em28xx_init_dev() were unlocking without a previous lock; - some read ioctls need to lock after the removal of KBL, since a write may be happening at the same time an ioctl is reading; - keep the device locked during all device initialization; - lock/unlock while reading/writing registers.

vidioc_try_fmt_vid_cap() just checks if a given resolution is supported. It doesn't touch on struct em28xx device descriptor. so, there's no need to lock. While there, use unlikely() for those values that aren't likely to occur. Signed-off-by: -

The zoom controls move the zoom lens group to a an absolute position, as a relative displacement or at a given speed until reaching physical device limits. Positive values move the zoom lens group towards the telephoto direction, negative values towards the wide-angle direction. Signed-off-by:

Refine the firmware load and firmware startup process. Significant changes are to ensure the SCB and IPC area are correct before starting up the firmware, and letting the CPU firmware start up the APU firmware for us. Signed-off-by:
