media: v4l: omap_vout: vrfb: initialize DMA flags

2017-08-08T10:35:10+00:00

Passing uninitialized flags into device_prep_interleaved_dma is clearly a bad idea, and we get a compiler warning for it: drivers/media/platform/omap/omap_vout_vrfb.c: In function 'omap_vout_prepare_vrfb': drivers/media/platform/omap/omap_vout_vrfb.c:273:5: error: 'flags' may be used uninitialized in this function [-Werror=maybe-uninitialized] It seems that the OMAP dmaengine ignores the flags, but we should pick the right ones anyway. This sets the flags I guessed based on what other drivers used, and Peter confirmed that they are the right ones.

[media] omap: don't break long lines

2016-10-21T11:31:11+00:00

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

mm: replace get_vaddr_frames() write/force parameters with gup_flags

2016-10-19T15:11:24+00:00

This removes the 'write' and 'force' from get_vaddr_frames() and replaces them with 'gup_flags' to make the use of FOLL_FORCE explicit in callers as use of this flag can result in surprising behaviour (and hence bugs) within the mm subsystem.
