      V4L/DVB (6070): Fix a warning at dvb_net · 04b35abe
      由 Mauro Carvalho Chehab 提交于 
      static function dvb_net_sec declares input arg "pkt" as u8. However, the
same argument at dvb_net_sec_callback is defined as "const u8". When
calling dvb_net_sec, this is casted as just "u8".

gcc 4.2.1 generates a warning about that:

  CC [M]  drivers/media/dvb/dvb-core/dvb_net.o
drivers/media/dvb/dvb-core/dvb_net.c: In function "dvb_net_sec_callback":
drivers/media/dvb/dvb-core/dvb_net.c:905: warning: passing argument 2 of
		"dvb_net_sec" discards qualifiers from pointer target type

      V4L/DVB (6042): b2c2-flexcop: fix Airstar HD5000 tuning regression · 6175e487
      由 Trent Piepho 提交于 
      Git changeset 6bdcc6e6 dropped the
stand-alone lgh06xf module, whose functionality was absorbed into the
dvb-pll module. However, there was a minor difference between the code
in lgh06xf and dvb-pll, which caused a regression in b2c2-flexcop
devices using the LG-H06xF NIM.

dvb-pll will probe for the presence of an i2c pll chip by performing a
single byte read, the lgh06xf driver did not do this. Unfortunately, the
code in flexcop-i2c.c does not currently support 1 byte or 0 byte reads
as a probe.  Such probes with the current code will always fail.

In order to work around this problem, and restore proper functionality
of the Airstar HD5000 device, this hack was created to make the probe
appear to succeed.  The single byte read in dvb_pll_attach is the only
place where such a probe would ever occur, so this change is safe, and
will not affect any other devices.

Of course, if one knew how to actually perform the read operation, it
would be better to go that route.  In the meantime, however, we must
apply this workaround, in order to prevent the regression that causes
tuning to fail on the Airstar HD5000 ATSC device.

Thanks to Jarod Wilson, who had originally reported this regression, and
to Geoffrey Hausheer, whose original workaround patch led us to find the
actual cause of the problem.
