Extend the error handling code with operations found in other nearby error handling code. A simplified version of the sematic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ @r@ statement S1,S2,S3; constant C1,C2,C3; @@ *if (...) {... S1 return -C1;} ... *if (...) {... when != S1 return -C2;} ... *if (...) {... S1 return -C3;} // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- This is only a suggestion. All of the other ways out of this function call wake_up(&buf->queue);. But I don't understand the code well enough to know why, or whether there is a reason not to do it in this case. drivers/media/dvb/ttpci/av7110_av.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/drivers/media/dvb/ttpci/av7110_av.c b/drivers/media/dvb/ttpci/av7110_av.c index 6ef3996..3ce5ccf 100644 --- a/drivers/media/dvb/ttpci/av7110_av.c +++ b/drivers/media/dvb/ttpci/av7110_av.c @@ -245,8 +245,11 @@ int av7110_pes_play(void *dest, struct dvb_ringbuffer *buf, int dlen) return -1; } while (1) { - if ((len = dvb_ringbuffer_avail(buf)) < 6) + len = dvb_ringbuffer_avail(buf); + if (len < 6) { + wake_up(&buf->queue); return -1; + } sync = DVB_RINGBUFFER_PEEK(buf, 0) << 24; sync |= DVB_RINGBUFFER_PEEK(buf, 1) << 16; sync |= DVB_RINGBUFFER_PEEK(buf, 2) << 8; -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
