Subject: [media] cx24120: make sure tuner is locked at get_frontend Author: Jemma Denson <[email protected]> Date: Sun Feb 28 15:29:50 2016 -0300 Change get_frontend to re-check current lock status rather than relying on a cached value from get_status. Removes potential for tuning failure if get_frontend is called during tuning. Probably not too essential as other changes work around this: https://patchwork.linuxtv.org/patch/32845/ Signed-off-by: Jemma Denson <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]> drivers/media/dvb-frontends/cx24120.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) --- http://git.linuxtv.org/cgit.cgi/media_tree.git/commit/?id=035cad576d4e8c472a97b8913f92f73c93205fd3 diff --git a/drivers/media/dvb-frontends/cx24120.c b/drivers/media/dvb-frontends/cx24120.c index 6ccbd86c9490..066ee387bf25 100644 --- a/drivers/media/dvb-frontends/cx24120.c +++ b/drivers/media/dvb-frontends/cx24120.c @@ -1507,11 +1507,13 @@ static int cx24120_get_frontend(struct dvb_frontend *fe, { struct cx24120_state *state = fe->demodulator_priv; u8 freq1, freq2, freq3; + int status; dev_dbg(&state->i2c->dev, "\n"); /* don't return empty data if we're not tuned in */ - if ((state->fe_status & FE_HAS_LOCK) == 0) + status = cx24120_readreg(state, CX24120_REG_STATUS); + if (!(status & CX24120_HAS_LOCK)) return 0; /* Get frequency */ _______________________________________________ linuxtv-commits mailing list [email protected] http://www.linuxtv.org/cgi-bin/mailman/listinfo/linuxtv-commits
