[media] b2c2: don't break long lines

2016-10-21T10:51:32Z

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. 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 $_; } Signed-off-by: Mauro Carvalho Chehab

[media] flexcop-i2c: mark printk continuation lines as such

2016-10-21T10:51:29Z

This driver has printk continuation lines for debugging purposes. Since commit 563873318d32 ("Merge branch 'printk-cleanups'"), this won't work as expected anymore. So, let's add KERN_CONT to those lines. Signed-off-by: Mauro Carvalho Chehab

[media] dvb-core: move dvb_filter out of the DVB core

2016-10-21T10:44:08Z

The dvb_filter.c can hardly be considered as part of the DVB core. More than half of the code there is commented out by av7110 and ttusb_dec. On the latter, just two small helper functions and a struct definition is used. Being part of the core means that it would require an amount of work to fix issues in it, like bad printk's on it, and to document it on some future, like other kAPI headers. It simply not worth the effort for something that seems to be deprecated, as no new drivers use it. So, move it out of the core, by moving it to pci/ttpci directory, where av7110 driver is kept, and copy the two routines used by ttyusb_dec directly into its code.

[media] b2c2: flexcop: avoid unused function warnings

2016-02-01T15:15:01Z

The flexcop driver has two functions that are normally used, except when multiple frontend drivers are disabled: drivers/media/common/b2c2/flexcop-fe-tuner.c:42:12: warning: 'flexcop_set_voltage' defined but not used [-Wunused-function] drivers/media/common/b2c2/flexcop-fe-tuner.c:71:12: warning: 'flexcop_sleep' defined but not used [-Wunused-function] This avoids the build warning by updating the #ifdef for flexcop_set_voltage to the exact condition under which it is used. For flexcop_sleep, the condition is rather complex, so I resort to marking it as __maybe_unused, so the compiler can silently drop it.

[media] b2c2: Add option to skip the first 6 pid filters

2015-06-09T23:57:56Z

The flexcop bridge chip has two banks of hardware pid filters - an initial 6, and on some chip revisions an additional bank of 32. A bug is present on the initial 6 - when changing transponders one of two PAT packets from the old transponder would be included in the initial packets from the new transponder. This usually transpired with userspace programs complaining about services missing, because they are seeing a PAT that they would not be expecting. Running in full TS mode does not exhibit this problem, neither does using just the additional 32. This patch adds in an option to not use the inital 6 and solely use just the additional 32, and enables this option for the SkystarS2 card. Other cards can be added as required if they also have this bug. Signed-off-by: Jemma Denson Signed-off-by: Mauro Carvalho Chehab

[media] dvb: Get rid of typedev usage for enums

2015-06-09T20:47:35Z

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.

[media] b2c2: Reset no_base_addr on skystarS2 attach failure

If set, all the other drivers reset no_base_addr on failure to attach - git commit for this being added to some of them seems to be eccd15aad72f774b2059f708bc422dbb8493bb30 This driver has been floating around outside the mainline for so long it hasn't had this fix, so add it in.
