Rework the pll algo selection so that the pll algo
in use can be selected more easily. This allows
us to select different pll divider selection algos
for specific monitors that work better with one algo
or the other. This is needed for the next patch which
adds an LVDS pll quirk for a specific notebook.

When running directed active scans we currently end up sending both the SSID
probe requests and an additional broadcast one.
This is due to the fact that we always leave the probe request template SSID IE
length to 0. Instead we should set it to the first SSID to scan, and fill the
direct_scan array with the remaining SSIDs to scan for. This way we only send
what we've been asked to: a broadcast probe request when no directed scan is
requested, and directed probe requests otherwise.

Retrying commands seldomly works, most often the firmware is in a

For debugging hardware scan trigger/complete

hwsim that pretends to do a hardware scan.
This code could be extended to actually do the

A DVB demultiplexer device can be used to set up either a PES filter or
a section filter. In the former case, the ts field of the feed union of
struct dmxdev_filter is used, in the latter case the sec field of the
same union is used.
The ts field is a struct list_head, and is currently initialized in the
open() method of the demux device. When for a given demuxer a section
filter is set up, the sec field is played with, thus if a PES filter
needs to be set up after that the ts field will be corrupted, causing a
kernel oops.
This fix moves the list head initialization to
dvb_dmxdev_pes_filter_set(), so that the ts field is properly
initialized every time a PES filter is set up.

dvb_dmx_init tries to allocate virtual memory for 2 pointers: filter and feed.
If the second vmalloc fails, filter is freed, but the pointer keeps pointing

free an already freed memory, causing an OOPS.
