[PATCH] block: partitions: efi: Typecast sizeof(gpt_header)

From: Fabio Estevam
Date: Wed Feb 20 2013 - 09:59:19 EST

From: Fabio Estevam <fabio.estevam@xxxxxxxxxxxxx>

Since commit ef25bb0fa6e2 (block/partitions/efi.c: ensure that the GPT header is
at least the size of the structure.) , when building for a 32-bit architecture,
such as ARM, the following build warning is seen:

block/partitions/efi.c:324:3: warning: format '%lu' expects argument of type 'long unsigned int', but argument 3 has type 'unsigned int' [-Wformat]

Typecast sizeof(gpt_header) to (unsigned long) to avoid such warning on 32-bit
