2016-10-21[media] firewire: don't break long linesMauro Carvalho Chehab1-2/+2
Due to the 80-cols restrictions, and latter due to checkpatch warnings, several strings were broken into multiple lines. This is not considered a good practice anymore, as it makes harder to grep for strings at the source code. As we're right now fixing other drivers due to KERN_CONT, we need to be able to identify what printk strings don't end with a "\n". It is a way easier to detect those if we don't break long lines. So, join those continuation lines. The patch was generated via the script below, and manually adjusted if needed. </script> use Text::Tabs; while (<>) { if ($next ne "") { $c=$_; if ($c =~ /^\s+\"(.*)/) { $c2=$1; $next =~ s/\"\n$//; $n = expand($next); $funpos = index($n, '('); $pos = index($c2, '",'); if ($funpos && $pos > 0) { $s1 = substr $c2, 0, $pos + 2; $s2 = ' ' x ($funpos + 1) . substr $c2, $pos + 2; $s2 =~ s/^\s+//; $s2 = ' ' x ($funpos + 1) . $s2 if ($s2 ne ""); print unexpand("$next$s1\n"); print unexpand("$s2\n") if ($s2 ne ""); } else { print "$next$c2\n"; } $next=""; next; } else { print $next; } $next=""; } else { if (m/\"$/) { if (!m/\\n\"$/) { $next=$_; next; } } } print $_; } </script> Reviewed-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Acked-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-10-21[media] firewire: use dev_dbg() instead of printk()Takashi Sakamoto1-2/+3
A structure for firedtv (struct firedtv) has a member for a pointer to struct device. In this case, we can use dev_dbg() for debug printing. This is more preferrable behaviour in device driver development.

2016-01-11[media] dvb: modify core to implement interfaces/entities at MC new genMauro Carvalho Chehab1-1/+1
The Media Controller New Generation redefines the types for both interfaces and entities to be used on DVB. Make the needed changes at the DVB core for all interfaces, entities and data and interface links to appear in the graph.

2015-06-09[media] dvb: Get rid of typedev usage for enumsMauro Carvalho Chehab2-6/+6
The DVB API was originally defined using typedefs. This is against Kernel CodingStyle, and there's no good usage here. While we can't remove its usage on userspace, we can avoid its usage in Kernelspace. So, let's do it. This patch was generated by this shell script: for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done While here, make CodingStyle fixes on the affected lines.

2014-11-25[media] firewire: Deletion of an unnecessary check before the function call ↵Markus Elfring1-2/+1
"dvb_unregister_device" The dvb_unregister_device() 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.

2014-09-23[media] firewire: firedtv-avc: fix more potential buffer overflowDan Carpenter1-2/+3
"program_info_length" is user controlled and can go up to 4095. The operand[] array has 509 bytes so we need to add a limit here to prevent buffer overflows. The " - 4" in the limit check is because we have 4 bytes more data to add after the memcpy(). [mchehab@osg.samsung.com: as I merged the version 1 of the patch, I needed to rebase to apply just the differences between v1 and v2] Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

2013-06-09firewire: introduce fw_driver.probe and .remove methodsStefan Richter1-10/+9
FireWire upper layer drivers are converted from generic struct driver.probe() and .remove() to bus-specific struct fw_driver.probe() and .remove(). The new .probe() adds a const struct ieee1394_device_id *id argument, indicating the entry in the driver's device identifiers table which matched the fw_unit to be probed. This new argument is used by the snd-firewire-speakers driver to look up device-specific parameters and methods. There is at least one other FireWire audio driver currently in development in which this will be useful too. The new .remove() drops the unused error return code. Although all in-tree drivers are being converted to the new methods, support for the old methods is left in place in this commit. This allows public developer trees to merge this commit and then move to the new fw_driver methods.

2013-04-08[media] demux.h: Remove duplicated enumMauro Carvalho Chehab1-7/+7
"enum dmx_ts_pes" and "typedef enum dmx_pes_type_t" are just the same enum declared twice, since Kernel (2.6.12). There's no reason to duplicate it there, and sparse complains about that: drivers/media/dvb-core/dmxdev.c:600:55: warning: mixing different enum types So, remove the internal define, keeping just the external one. Internally, use only "enum dmx_ts_pes", as it is too late to drop dmx_pes_type_t from the userspace API. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-10-19[media] remove include/linux/dvb/dmx.hMauro Carvalho Chehab1-0/+1

2012-08-17[media] Fix some Makefile rulesMauro Carvalho Chehab1-1/+1
On a few places, := were using instead of +=, causing drivers to not compile. While here, standardize the usage of += on all cases where multiple lines are needed, and for obj-y/obj-m targets, and := when just one line is needed, on <module>-obj rules.
