[libdvdnav-devel] [PATCH] libdvdread: dvd_udf.c - comment out unused macro

[Steve Dibb]

Fixes warning:

src/dvd_udf.c:322:9: warning: macro is not used [-Wunused-macros]
#define GETN3(p) ((uint32_t)data[p] | ((uint32_t)data[(p) + 1] << 8)    \
         ^

Comments out the macro, but leaves it in the code as a point of 
reference, if needed:
