media: drxk: Does not unlock mutex if sanity check failed in scu_command()

2012-04-27T17:16:37+00:00

commit e4459e1682c107d7ee1bf102c1ba534230e9b50b upstream.

If sanity check fails in scu_command(), goto error leads to unlock of
an unheld mutex. The check should not fail in reality, but it nevertheless
worth fixing.

au8522: bug-fix: enable modulation AFTER tune (instead of before tuning)

2012-04-02T17:32:09+00:00

commit ef3d2dc366c8c32d58dbbf9898cfd4f853ff8fe0 upstream.

The au8522 driver programs the tuner after programming the demodulator,
but the tuner should be programmed first. This patch fixes this behavior.

EDIT: Apparantly Devin created a similar patch some time ago, but hasn't
submitted it for merge.  I never saw his patch, but I thank him anyhow
for his efforts.  In addition, Devin pointed out a flaw in my patch:

This newly generated patch takes Devin's comments into account.

Thanks-to: Devin Heitmueller

tda10071: fix the delivery system

2012-04-02T17:32:09+00:00

commit 2b49fad59513b07f976c9711b99f93ae74d081c5 upstream.

Commit b2a29b578d9c21b2e5c88020f830d3c42115c51d sets accidentally
supported delivery systems as DVB-T/T2 whilst it should be
DVB-S/S2. Due to that frontend cannot be used at all.

lgdt330x: fix signedness error in i2c_read_demod_bytes()

2012-04-02T17:32:09+00:00

commit 34817174fca0c5512c2d5b6ea0fc37a0337ce1d8 upstream.

The error handling in lgdt3303_read_status() and lgdt330x_read_ucblocks()
doesn't work, because i2c_read_demod_bytes() returns a u8 and (err < 0)
is always false.

        err = i2c_read_demod_bytes(state, 0x58, buf, 1);
        if (err < 0)
                return err;

Change the return type of i2c_read_demod_bytes() to int.  Also change
the return value on error to -EIO to make (err < 0) work.

[media] cxd2820r: sleep on DVB-T/T2 delivery system switch

2012-01-23T20:10:52+00:00

Fix bug introduced by multi-frontend to single-frontend change.
It is safer to put DVB-T parts sleeping when auto-switching to DVB-T2
and vice versa. That was original behaviour.

[media] ds3000: using logical && instead of bitwise &

2012-01-18T01:05:13+00:00

The intent here was to test if the FE_HAS_LOCK was set.  The current
test is equivalent to "if (status) { ..."

[media] cxd2820r: do not allow get_frontend() when demod is not initialized

2012-01-16T14:55:47+00:00

This fixes bug introduced by multi-frontend to single-frontend change.

Finally HAS_LOCK is got back!
We are not allowed to access hardware in sleep mode...
Chip did not like when .get_frontend() reads some registers while
chip was sleeping and due to that HAS_LOCK bit was never gained.

TODO: We should add logic for dvb-core to drop out illegal calls like that.
