* | [media] m88ds3103: One function call less in m88ds3103_init() after error ↵Markus Elfring2014-11-25
| | | | | | | | | | | | | | | | | | | | | | | | | | detection GIT_AUTHOR_DATE=1416472158 The release_firmware() function was called in some cases by the m88ds3103_init() function during error handling even if the passed variable contained still a null pointer. This implementation detail could be improved by the introduction of another jump label.

| | | | | | | | | | | | | | | | | | | | | | | | | | call "release_firmware" GIT_AUTHOR_DATE=1416472432 The release_firmware() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.

| | | | | | | | | | | | | | | | | | 1> When m88ds3103 works in serial ts mode, its serial ts clock is equal to ts master clock and the clock divider is bypassed. 2> The serial ts clock is configed by the bridge driver just like parallel ts clock.

* | [media] m88ds3103: add support for the demod of M88RS6000nibble.max2014-11-03
|/ | | | | | | | | | | | | | | | | | M88RS6000 is the integrated chip, which includes tuner and demod. Its internal demod is similar with M88DS3103 except some registers definition. The main different part of this internal demod from others is its clock/pll generation IP block sitting inside the tuner die. So clock/pll functions should be configed through its tuner i2c bus, NOT its demod i2c bus. The demod of M88RS6000 need the firmware: dvb-demod-m88rs6000.fw firmware download link: http://www.dvbsky.net/download/linux/dvbsky-firmware.tar.gz Signed-off-by: Nibble Max <nibble.max@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

* [media] m88ds3103: possible uninitialized scalar variableAntti Palosaari2014-03-12
| | | | | | | | | | | | | It was possible that tuner_frequency variable, used for carrier offset compensation, was uninitialized. That happens when tuner .get_frequency() callback is not defined. Currently that case is not possible as only used tuner has this callback.
