Mauro Carvalho Chehab 89d6e45c8a media: sp887x: fix a warning
drivers/media/dvb-frontends/sp887x.c:179 sp887x_initial_setup() error: memcpy() '&buf[2]' too small (30 vs 16384)

This is actually a false alarm, but reverting the check order
makes not only for humans to review the code, but also cleans
the warning.

Rework both DiSEqC send functions (send_master_cmd() and send_burst()) to
utilise the new SET_REG() and SET_FIELD() macros. Esp. due to SET_FIELD(),
this makes sure that not all bits (with unrelated purposes) are always
rewritten, but only those needed for sending DiSEqC commands. In
send_burst(), this makes sure that DISEQC_MODE isn't changed from 3 to 2
inbetween when sending SEC_MINI_A. Also, change both functions to write
DISEQC_MODE first before setting DIS_PRECHARGE. This makes diseqc control
work more reliable for "fullblown" DiSEqC strings in VDR's diseqc.conf in
combination with certain multiswitches.

Fixes: 448461af0e ("media: dvb-frontends/stv0910: implement diseqc_send_burst")

Daniel Scheller 15f757bb5a media: cxd2099: move driver out of staging into dvb-frontends
According to the TODO file, this driver only landed in staging because of
the way device nodes and data transfers are handled. Besides that this way
(use of secX devices) has become sort of standard to date (ie. VDR
supports this literally since ages via the ddci plugin, TVHeadend received
this functionality lately, and minisatip being currently worked on
regarding this), most importantly this I2C client only driver isn't even
responsible for setting up device nodes, not for handling data
transfer and so on, but only serves as interface for the dvb_ca_en50221
subsystem, just like every other DVB card out in the wild, with hard-wired
or such flexible CA interfaces. And, it would even work with cards having
the cxd2099 controller hard-wired.

Also, this driver received quite some love and even is a proper I2C client
driver by now. So, as this driver acts as a EN50221 frontend device, move
it to dvb-frontends. There is no need to keep it buried in staging.

This commit also updates all affected Kconfig and Makefile's, and adds
MEDIA_AUTOSELECT depends to ddbridge and ngene.

There is a typo at the several s5h14*.h headers: continuous were
spelled incorrectly.

Fix it with this script:

for i in $(git grep -l S5H1409_MPEGTIMING_CONTINOUS_NONINVERTING_CLOCK); do
	sed s,S5H1409_MPEGTIMING_CONTINOUS_NONINVERTING_CLOCK,S5H1409_MPEGTIMING_CONTINUOUS_NONINVERTING_CLOCK,g -i $i
done
for i in $(git grep -l -i continous drivers/media); do sed s,CONTINOUS,CONTINUOUS,g -i $i; done

Brad Love 94448e21cf media: lgdt3306a: Fix a double kfree on i2c device remove
Both lgdt33606a_release and lgdt3306a_remove kfree state, but _release is
called first, then _remove operates on states members before kfree'ing it.
This can lead to random oops/GPF/etc on USB disconnect.

Brad Love 835d66173a media: lgdt3306a: Fix module count mismatch on usb unplug

increments the usage count so it is properly balanced on removal.

Brad Love 4966c0c5c6 media: lgdt3306a: Add QAM AUTO support
As configured currently, modulation in the driver is set to auto detect,
no matter what the user sets modulation to. This leads to both QAM64
and QAM256 having the same effect. QAM AUTO is explicitly added here for
compatibility with scanning software who can use AUTO instead of doing
essentially the same scan twice.
Also included is a module option to enforce a specific QAM modulation if
desired. The true modulation is read before calculating the snr.
Changes are backwards compatible with current behaviour.

Brad Love 5b3a8e9069 media: lgdt3306a: Set fe ops.release to NULL if probed
If release is part of frontend ops then it is called in the
course of dvb_frontend_detach. The process also decrements
the module usage count. The problem is if the lgdt3306a
driver is reached via i2c_new_device, then when it is
eventually destroyed remove is called, which further
decrements the module usage count to negative. After this
occurs the driver is in a bad state and no longer works.
Also fixed by NULLing out the release callback is a double
kfree of state, which introduces arbitrary oopses/GPF.
This problem is only currently reachable via the em28xx driver.

lsmod | grep lgdt3306a
lgdt3306a              28672  -1

Dan Gopstein 7aa92c4229 media: ABS macro parameter parenthesization
Replace usages of the locally defined ABS() macro with calls to the
canonical abs() from kernel.h and remove the old definitions of ABS()

This change was originally motivated by two local definitions of the
ABS (absolute value) macro that fail to parenthesize their parameter
properly. This can lead to a bad expansion for low-precedence
expression arguments.

For example: ABS(1-2) currently expands to ((1-2) < 0 ? (-1-2) : (1-2))
which evaluates to -3. But the correct expansion would be
((1-2) < 0 ? -(1-2) : (1-2)) which evaluates to 1.

Daniel Scheller 62474660fb media: dvb-frontend/mxl5xx: add support for physical layer scrambling
The MaxLinear MxL5xx has support for physical layer scrambling, which was
recently added to the DVB core via the new scrambling_sequence_index
property. Add required bits to the mxl5xx driver.

Picked up from dddvb master, commit 5c032058b9ba ("add support for PLS")
by Ralph Metzler <rjkm@metzlerbros.de>, adapted to the different naming
of the pls property (pls vs. scrambling_sequence_index).
