kernel-doc: bugfix - multi-line macros
Prior to this patch the following code breaks:
/**
* multiline_example - this breaks kernel-doc
*/
#define multiline_example( \
myparam)
Producing this error:
Error(somefile.h:983): cannot understand prototype: 'multiline_example( \ '
This patch fixes the issue by appending all lines ending in a blackslash
(optionally followed by whitespace), removing the backslash and any
whitespace after it prior to appending (just like the C pre-processor
would).
This fixes a break in kerel-doc introduced by the additions to rbtree.h.
