Set the v4l2_device already in async notifier init, so struct device
related to it will be available before the notifier is registered.
This is done in order to make struct device available earlier, during
construction of the async connections, for sensible debug prints.
This patch has been mostly generated using the following two commands:
git grep -l v4l2_async_nf_init -- drivers/media/ drivers/staging/media/ |
while read i; do perl -e '
@a=<>; unlink("'$i'"); open(F, "> '$i'");
for $f ({i=>"v4l2_async_nf_init", r=>"v4l2_async_nf_register"},
{i=>"v4l2_async_subdev_nf_init",
r=>"v4l2_async_subdev_nf_register"} ) {
my $b; @a = map { $b = "$1, $2" if
s/$f->{r}\(([^,]*),\s*([^\)]*)\)/v4l2_async_nf_register\($2\)/;
$_; } @a; @a = map { if (defined $b) {
s/v4l2_async_nf_init\([^\)]*\)/$f->{i}\($b\)/;
s/$f->{r}\(\K[^,]*,\s*//; }; $_; } @a; }; print F @a; close F;'
< $i; done
git grep -lP 'v4l2_async_(subdev_|)nf_init' | xargs perl -i -pe \
's/v4l2_async_(subdev_|)nf_init\(\K([^,]*),\s*([^,]*)\)/$3, $2\)/'
