The code to modify the b43 related bug is commented out. I got help
writing the sed line, and I have NFI what it does. I'm not putting it
in without understanding.
Sed FAQ [1] 4.13 sheds some light on that. In pseudocode:
for each input line
buffer = input line
:more
if not last line
buffer += next line
// string to be replaced consists of 3 lines
if buffer contains 3 lines (or: 2 end-lines)
goto enough
goto more
:enough
buffer.replace(b43err..., See http...)
print buffer
delete buffer
Or in plain words: get 3 consecutive lines, check if it's the string you
want to replace and replace if it is.
But the patch as it is now (if uncommented) won't work. First of all, it
doesn't provide input for sed. This will make it wait for input. You
probably want:
sed -i '/CONFIG_VIDEO_CX23885/d' ./drivers/media/video/Makefile
+
+# Stop b43 ...
+sed -i ':more...' ./drivers/net/wireless/b43/main.c
+
+# Remove ...
+...
cd ..
Secondly, the search string as it is now doesn't take the whitespace in
the code into account. I think that it should be something like:
s|.*b43err...to "\n.*"http...firmware "\n.*and..\\n");|See...|;
