From 4d5ded751e8651707d5b6b59bcd45576c1b04bff Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 18 Oct 2016 17:44:17 -0200 Subject: [PATCH] [media] hdpvr: don't break long lines 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 --- drivers/media/usb/hdpvr/hdpvr-core.c | 9 +++------ drivers/media/usb/hdpvr/hdpvr-i2c.c | 7 +++---- drivers/media/usb/hdpvr/hdpvr-video.c | 4 +--- 3 files changed, 7 insertions(+), 13 deletions(-) diff --git a/drivers/media/usb/hdpvr/hdpvr-core.c b/drivers/media/usb/hdpvr/hdpvr-core.c index a61d8fd63c12..15f016ad5b89 100644 --- a/drivers/media/usb/hdpvr/hdpvr-core.c +++ b/drivers/media/usb/hdpvr/hdpvr-core.c @@ -41,13 +41,11 @@ MODULE_PARM_DESC(hdpvr_debug, "enable debugging output"); static uint default_video_input = HDPVR_VIDEO_INPUTS; module_param(default_video_input, uint, S_IRUGO|S_IWUSR); -MODULE_PARM_DESC(default_video_input, "default video input: 0=Component / " - "1=S-Video / 2=Composite"); +MODULE_PARM_DESC(default_video_input, "default video input: 0=Component / 1=S-Video / 2=Composite"); static uint default_audio_input = HDPVR_AUDIO_INPUTS; module_param(default_audio_input, uint, S_IRUGO|S_IWUSR); -MODULE_PARM_DESC(default_audio_input, "default audio input: 0=RCA back / " - "1=RCA front / 2=S/PDIF"); +MODULE_PARM_DESC(default_audio_input, "default audio input: 0=RCA back / 1=RCA front / 2=S/PDIF"); static bool boost_audio; module_param(boost_audio, bool, S_IRUGO|S_IWUSR); @@ -165,8 +163,7 @@ static int device_authorization(struct hdpvr_device *dev) dev->flags |= HDPVR_FLAG_AC3_CAP; break; default: - v4l2_info(&dev->v4l2_dev, "untested firmware, the driver might" - " not work.\n"); + v4l2_info(&dev->v4l2_dev, "untested firmware, the driver might not work.\n"); if (dev->fw_ver >= HDPVR_FIRMWARE_VERSION_AC3) dev->flags |= HDPVR_FLAG_AC3_CAP; else diff --git a/drivers/media/usb/hdpvr/hdpvr-i2c.c b/drivers/media/usb/hdpvr/hdpvr-i2c.c index 9b641c4d4431..fcab55038d99 100644 --- a/drivers/media/usb/hdpvr/hdpvr-i2c.c +++ b/drivers/media/usb/hdpvr/hdpvr-i2c.c @@ -145,15 +145,14 @@ static int hdpvr_transfer(struct i2c_adapter *i2c_adapter, struct i2c_msg *msgs, msgs[0].len); } else if (num == 2) { if (msgs[0].addr != msgs[1].addr) { - v4l2_warn(&dev->v4l2_dev, "refusing 2-phase i2c xfer " - "with conflicting target addresses\n"); + v4l2_warn(&dev->v4l2_dev, "refusing 2-phase i2c xfer with conflicting target addresses\n"); retval = -EINVAL; goto out; } if ((msgs[0].flags & I2C_M_RD) || !(msgs[1].flags & I2C_M_RD)) { - v4l2_warn(&dev->v4l2_dev, "refusing complex xfer with " - "r0=%d, r1=%d\n", msgs[0].flags & I2C_M_RD, + v4l2_warn(&dev->v4l2_dev, "refusing complex xfer with r0=%d, r1=%d\n", + msgs[0].flags & I2C_M_RD, msgs[1].flags & I2C_M_RD); retval = -EINVAL; goto out; diff --git a/drivers/media/usb/hdpvr/hdpvr-video.c b/drivers/media/usb/hdpvr/hdpvr-video.c index 474c11e1d495..e3e7682d0f0e 100644 --- a/drivers/media/usb/hdpvr/hdpvr-video.c +++ b/drivers/media/usb/hdpvr/hdpvr-video.c @@ -336,9 +336,7 @@ static int hdpvr_stop_streaming(struct hdpvr_device *dev) buf = kmalloc(dev->bulk_in_size, GFP_KERNEL); if (!buf) - v4l2_err(&dev->v4l2_dev, "failed to allocate temporary buffer " - "for emptying the internal device buffer.
