Check return value of asprintf() in docsect() and exit if error occurs. This removes following warning:
HOSTCC scripts/basic/docproc scripts/basic/docproc.c: In function ‘docsect’: scripts/basic/docproc.c:336: warning: ignoring return value of ‘asprintf’, declared with attribute warn_unused_result
Signed-off-by: Namhyung Kim <namhyung@gmail.com> --- The patch is on top of v2.6.36, thanks.
